It is a VAZ or a foreign car. This manifests itself in uneven operation of the engine. One or even several cylinders do not work. Due to the fact that the engine troit - fuel consumption increases greatly. The power and traction characteristics of the engine decrease. The engine can troit both at idle and at speed or when cold. One of the reasons why the engine runs unevenly is the spark plugs. Yes, yes, exactly the spark plugs. The simplest and most banal reason. Remove the spark plugs and check them. If they are black or have a lot of carbon deposits, they definitely need to be replaced. The spark plugs may also have a very large gap, as the spark does not penetrate such large gaps well. How to diagnose correctly: https://www.youtube.com/edit?o=U&vide... In addition to spark plugs, high-voltage wires or the ignition module will also be the cause of misfiring. It is very easy to check the wires - you need to measure their resistance with a regular tester. If there is a break in any wire, you will definitely see it. The resistance of the wires should be several kilo-ohms (2-7 kOhm). You can check the ignition module by rearranging the wires on it and checking in which of the cylinders there is no spark. If you rearranged the wires, but there is still no spark in the same cylinder, then it is highly likely that the ignition module is broken. Another reason for the engine to misfire is bad gasoline or an incorrect composition of the fuel-air mixture. If you fill up with bad fuel, then debris from it can easily clog one or more injectors. For information on cleaning injectors, see here: https://www.youtube.com/edit?o=U&vide... Also, if the timing marks are knocked down, the engine will also run rough or unevenly. The engine will shake if the timing marks are incorrect. This is a consequence of either the damper turning or the timing belt slipping. I have already said about the injectors - if they are clogged or there is a break in the wiring, the injectors do not work and the engine jerks. Well, a sharp difference in compression between the cylinders leads to the fact that the engine begins to run extremely unstable.
