Problems with cars are always unpleasant, and when the 8-valve engine on a Kalina, which has not yet driven 50,000 kilometers, fails, it is also insulting. But this problem does not appear immediately, but only when the engine warms up a little. Then the “engine malfunction” light starts flashing.
Turning off the ignition and restarting the car immediately solves the problem. Or rather, it stops for a minute, but then the games with nerves begin again.
The 8-valve engine on Kalina troubles only after the engine has slightly warmed up. In the very first minutes of starting, there is no such feeling: the power unit runs smoothly, the speed is kept at the same level. However, later the tachometer needle begins to twitch, rattling begins, and the engine itself begins to throttle and choke on fuel.
Finding the cause of the malfunction
The engine starts to stall when the fuel pump malfunctions and does not pump in the required amount of fuel, or when it does not burn completely. The substrate of the first case is not only the fuel pump itself, but also the conductive system. And the second reason may be related to problems with the ignition system, spark plug carbon, or improper operation of the engine valves.
If the fuel system is not working properly
, the feeling that the engine is stalling will develop a minute after the start, and then will only increase. If there is a narrowing of the pipeline, or there is no power to the fuel pump, such problems are not uncommon. You can check this after exposing the relay: start the engine, check the functionality of the pump and relay. In this case, the on-board computer will not show errors.
If there is a problem in the valve apparatus itself, in the spark plugs or in the ignition system, it will also manifest itself. Namely: the engine will start normally, but a moment later it will start to stall. Similarly, the power unit fault light should light up, because standard sensors perceive an excess (or lack) of fuel.
When such interruptions in the fuel supply occur, twitching develops, because the amount of gases produced in different engine operating cycles varies.
List of possible problems
Troubles the engine
Problem. After filling up with new gasoline, the check engine light started to come on, the car managed to warm up, but it started to stall after about 20-30 minutes of driving. Answer. In this case, it is not the ignition; the power supply and gas distribution system can also be discarded. It is necessary to check the integrity of the carburetor and fuel supply system. Replacing gasoline sometimes does not solve the problem.
This happens in some foreign cars with automatic transmissions. If you can’t find anything on your own, you should go to a service station; computer diagnostics should reveal the problem. There is no need to agree to replacing components without a reason, if the option will only possibly solve the problem. It is recommended to visit another service station.
Problem. Gasoline engine, injection type, misfires are shown in different cylinders during diagnostics. The spark plugs were replaced, all parts of the gas distribution system were cleaned and checked. Answer. The breakdown may be in the distributor cover or the ignition power supply: wiring, coils. It remains to check the fuel system as well.
Engine tripping is a very unpleasant defect that is difficult to get rid of. It is necessary to check all the above components, replace damaged parts - perhaps this will solve the problem. If all attempts are in vain, then you should go to a service station for diagnostics.
Problems with valves on Lada Kalina
On the 8-valve Lada Kalina engine, the valves are less reliable than on the 16-valve version. This is a design flaw of engineers that car enthusiasts will have to deal with.
For diagnostics, you will need to at least look at the electronic control unit and compression in the cylinders. This will have to be done at a car service center, where computer diagnostics will initially be offered (see the article “What is included in engine diagnostics”).
Often, there is no result that can be relied upon to fix the problem, because the source of the breakdown is not in the sensors, but in the mechanical part of the car. Therefore, you will have to measure the compression in the cylinders. If it is normal, you need to remove the engine valve cover and inspect the gap between the valves. Its normal value is 0,2-0,35
.
It is important to set the valve clearance in this range, after which the engine stops running and the “engine malfunction” light goes out. By the way, valve adjustment for Kalina is required every 60,000-70,000 kilometers. But when gas is used as fuel, they need to be adjusted more often - every 20,000-30,000 km.

At about zero temperature, it takes a long time to start and stalls without the gas pedal until it warms up. When hot, everything is fine: it starts normally and drives fine. At temperatures below -10C, starting is a pain, but at -20C it is impossible to start.
This has been a problem for several years now, so the problem is not with gasoline. The following was done: - pressure measurement - 3.7 atm - DTOZh readings (adequate to the temperature), mass air flow sensor - 1.016V (changed for a new one - no problem) - coil, explosive wires, spark plugs - new - DPKV - new
— software in the ECU is native (full).
The only problem is that the compression in one of the cylinders is 4 units lower than in the others.
We haven't dug any deeper yet. Good advice is welcome.

The valve burned out. Check the valves in the overlap and in the spark plug with a pneumatic tester - listen in the muffler.
If we discard the compression information -
RXX (biting in cold weather)
Flipping the ECU (this happened several times, sometimes “taking” the ECU home at night helps)

To write “normal” is wrong. How much exactly?
The compression is exactly how much it is cylinder by cylinder. A difference of 4 is already a lot.
Without a pedal - most often IAC.
Remove the ECU, open it and look for coolant. Kalina however.

To write “normal” is wrong. How much exactly?
Yes, the engine should start on 3 cylinders. The IAC was also changed.
The fact is that from -5C, pressing the gas pedal has no effect on starting.
The ECU is normal - no traces of antifreeze.

Timing belt? At TDC DPKV on the 20th tooth? Have you changed the injectors?
Replace the ECU. Are the spark plugs damp after not starting?
What color are they after the engine is running?

Causes of tripping at idle
Engine problems when idling
When you turn on the ignition and start the car, it idles intermittently. There may be several reasons for this . Let's consider the main problems that lead to this effect:
- Problems with spark plugs.
Diagram of possible spark plug faults
All these reasons can cause the engine to idle intermittently.
Trouble-shooting
The causes of the malfunction have been identified, and you can proceed to repair the car. To do this, it is worth checking step by step all the elements that could cause such an effect. So, let's look at the sequence of actions to troubleshoot the problem.
Spark plug
A breakdown, contamination or failure of this element can lead to the car idling intermittently, or, in popular parlance, “triple”. To eliminate the problem, you need to unscrew the spark plugs. How to do it:
- Remove the negative terminal from the battery.
Removing the battery terminal
We take out the high-voltage wires
Removing spark plugs using a 21 socket
That's basically all the dismantling operations.
In order to understand the condition of the spark plug, you need to visually inspect it: if it is too dirty, it means that they are being filled with gasoline and it cannot detonate normally, but if it is too clean, then not enough fuel gets into the engine.
Also, it is imperative to check the performance of the spark plugs. This is done on a spark plug stand, but if there is no such thing, then the old fashioned way, using a tester, we measure the resistance. It is imperative to measure the spark plug gap using a feeler gauge with a mark of 0.10 - this is the standard size that should be on all elements.
High voltage wires
The serviceability of high-voltage wires is checked by checking the resistance. Using a tester, each wire is “ringed” separately, where the value should be 5 ohms.
Checking high voltage wires
Ignition coil
If this unit fails or malfunctions, the effect of poor performance may occur not only at idle, but also when driving. It is worth checking the performance of the coil and replacing it if necessary.
Fuel system
The most common problems with engine rough idling occur in the fuel system. There may be several reasons for this, namely:
Checking and cleaning injectors yourself
Fuel pump filter clogged
It is worth checking all these elements for normal operation. If necessary, troubleshoot any problems that may arise.
Elimination of tripping
Why does the Lada Kalina 2 engine fail? Since computer diagnostics and replacement of damaged elements did not produce results, it is worth checking the mechanics that caused the malfunction.
Fuel system
Recently, many car owners have begun to complain about tripping, although the vehicle is almost new. The occurrence of such a malfunction is primarily associated with low-quality fuel, which is sold at gas stations. Such gasoline negatively affects not only the entire fuel system, but also the condition of the combustion chamber. So, due to long-term use of such “liquid”, valves and pistons burn out, and oil scraper rings become unusable.
Fuel system Lada Kalina 2.
First, it’s worth examining the condition of the fuel pump, or rather the mesh filter placed on it. It is a clogged element that may not allow enough fuel to pass through. Therefore, it is recommended to replace the element, especially since its cost is low and affordable.
The next element that is worth checking are the injectors. They can become clogged not only due to the use of low-quality fuel, but also wear out during operation. Dirty injectors produce a lean mixture, which can cause tripping. Cleaning of elements is carried out on a special stand, so for high-quality cleaning it is recommended to contact specialists.
Air supply
Contamination of the air supply system can cause the engine to choke and tripping to occur. Thus, it is recommended to examine the condition of the air filter, because if it is clogged, this prevents the engine from receiving the required amount of oxygen.
Clogged air filter Lada Kalina 2.
The next component, the failure of which can lead to tripping, is the throttle valve. This element may become clogged or worn out during operation. Thus, jamming of a part will lead to a constant single air flow, which may be too little or too much for operating the motors. Therefore, diagnostics and cleaning of spare parts is periodically necessary.
Spark generator
In this unit, spark plugs and high-voltage wires play an important role. The malfunction of these two elements is the cause of many problems, such as tripping. Therefore, to eliminate the breakdown, it is necessary to dismantle the elements from the vehicle.
To eliminate the causes, it is necessary to clean the contact group and install the elements in place. If there is no spark or there are cracks, then it is worth replacing the damaged spare parts, having first checked the new ones and set the necessary clearances.

Video review on the question “Why does Kalina trip when starting up”
After writing the article, I decided to also make a video review, where I told the whole story in detail.
If my experience was useful to someone, I was happy to help.
Why the engine stall
Lada Kalina
Kalina engine is having problems - most of the drivers of this Russian car have encountered this problem. With all this, it should be noted that a similar problem is not a proprietary problem of this model, because it is quite common in both other Russian cars and foreign cars.
Prevention of car engine tripping
Prevention of such a phenomenon as engine “triplication” is that the car owner needs to promptly eliminate the most common malfunctions of the engine, as well as other related systems. To do this, it is necessary to strictly adhere to the periodic maintenance schedules established by the manufacturer for the vehicle. At the same time, if you have little experience in owning a car, it is better not to engage in serious technical work yourself, but to entrust their implementation to experienced specialists.
In addition, it makes sense not to delay carrying out prevention at the first deterioration in engine performance, attributing them, for example, to low-quality gasoline. At the same time, all preventive measures should be carried out only in those auto repair shops where experienced craftsmen work. For example, incorrectly set ignition timing can lead to the appearance of “triple”. Unqualified service station employees very often sin with this, especially if the car owner is a novice behind the wheel and has little understanding of the technical side of the matter.
In the same case, when all systems and components of Kalina work correctly, the “triple” effect should not occur. In this case, the service life of the engine should be significantly reduced, since the power unit, in which one of the cylinders is inoperative, may experience increased loads, leading to its accelerated failure.
It is worth mentioning the Traffic Rules, which directly prohibit the operation of a vehicle with a faulty engine. Therefore, it is better not to risk either money or rights, and if a “triple” effect occurs, immediately send the car for repairs.
Problems with cars are always unpleasant, and when the 8-valve engine on a Kalina, which has not yet driven 50,000 kilometers, fails, it is also insulting. But this problem does not appear immediately, but only when the engine warms up a little. Then the “engine malfunction” light starts flashing.
Turning off the ignition and restarting the car immediately solves the problem. Or rather, it stops for a minute, but then the games with nerves begin again.
Signs of a malfunction
Kalina car has an engine problem
, this means that its engine only has 3 cylinders instead of 4. This is due to defects in the machine’s unit, which can manifest itself in the appearance of extraneous noise both when driving and while idling.
The main signs of “tripleting” are the following:
- failures to start the engine of various natures, accompanied by extremely strong vibrations transmitted to the vehicle interior;
- all cases when the engine ;
- blackening of one of the candles;
- a change in the sound of the exhaust, while an experienced auto mechanic can even determine by the sound of a running engine that it has some kind of defect;
- deterioration in the dynamic and speed characteristics of Kalina, a sharp increase in fuel consumption in all modes;
- “strange” readings from instruments, such as the tachometer;
- jerking during acceleration in any gear engaged.
If at least one of the listed signs appears, you should immediately stop using the car and send it for a comprehensive diagnosis. The fact is that the symptoms described can serve as signs of the appearance of a variety of engine defects, which can masquerade as other malfunctions. For example, a burnt spark plug may simply be replaced or cleaned by the car owner without identifying the reasons for this phenomenon, and at this time the car’s engine may already be seriously damaged.
It is worth talking separately about those cases when the presence of a malfunction is signaled by the automatic diagnostic system installed on Kalina. If the engine icon lights up on the dashboard, you should immediately stop driving and call a tow truck to transport the car to a car service center. The fact is that it is there that they can reliably decipher the sensor readings and establish why the check engine light is on.
The main consequences of operating a “triple” engine can be increased wear of its rubbing parts, that is, rings, piston and cylinder. The fact is that the idle cylinder still receives gasoline, which washes away the protective layer of oil from them. As a result, it is quite possible that the entire cylinder will have to be replaced, and in the worst case, the same fate awaits the entire power unit.
What can cause "triple"?
The causes of the described malfunction can be very different.
To reliably install them, you must first find the faulty cylinder. It is recommended to start such a search from the very moment when it was discovered that the check engine light was on. At least, such recommendations are given by the manufacturer who installed an automatic fault warning system on the car.
The search procedure is quite simple. To do this, it is enough to disconnect the power tips from the spark plugs one by one. As a result of this alternate shutdown, it is possible to determine the inoperative cylinder by the sound of the engine. If the sound of the engine has changed, this means that the culprit of the “triple” has been detected.
If the check light on Kalina is on and computer diagnostics of the engine is carried out, the faulty cylinder will be indicated by the computer. At the same time, this diagnostic method can also help to establish the initial causes that led to its malfunction. They could be the following:
- incorrectly set ignition timing;
- presence of air leaks in the vacuum brake booster;
- defective spark plugs;
- breakdown of electrical wiring and capacitor wires;
- presence of air in the exhaust manifold;
- wear or breakage of piston rings;
- burnout of pistons and valves;
- incorrect valve timing;
- cylinder head defects;
- severe wear of the valve stem seals;
- poor carburetor adjustment;
- air filter contamination;
- use of spark plugs incompatible with this engine.
In this case, the main malfunction leading to the fact that one of the cylinders becomes inoperable is considered to be the failure of the spark plugs. A sign of this may be the fact that Kalina’s engine does not warm up well, especially in the morning.
In addition, it is always worth making sure that when operating a car, only those spark plugs that are recommended by the manufacturer are used. This can extend the life of the engine for a very long time.
