What is the cause of engine jitter in Zhida x3?

Engine carbon deposition is serious;

The most common cause of automobile jitter is that the throttle valve is too dirty or the fuel injector has too much carbon deposit. When there is too much carbon deposit in the engine, the gasoline sprayed by the fuel injection head will be absorbed by a large amount of carbon deposit during cold start, which leads to too thin mixture during cold start and difficult start. In this case, it is easy to start the car only if the gasoline with carbon deposits is saturated. After the car is started, the gasoline adsorbed on the carbon deposit will be sucked into the cylinder by the engine's real inhalation for combustion, which will thicken the mixture and dilute and thicken the combustible mixture of the engine, resulting in a cold start. The lower the temperature, the more oil is needed for cold start, and the more carbon deposit will affect the success of cold start.

Ignition system problem:

Check the working conditions of spark plugs, high-voltage lines and ignition coils. If the ignition system is not good and the spark plug does not jump, it will also lead to such a failure.

Unstable oil pressure:

Such as cleaning engine carbon deposit, cleaning throttle, replacing oil pad and spark plug, etc. But also found idle jitter. I suggest you go to the 4S shop to check whether the fuel supply pressure and intake pressure sensors are normal. If the oil supply pressure of the oil pump is abnormal, or the value of the intake pressure sensor is incorrect and works poorly, it will cause the body to shake.
