Skoda Ming Rui Engine Idle Jitter

What is the cause of engine jitter in Skoda Ming Rui? The reason of engine jitter of Skoda Ming Rui is as follows: 1. The engine has a serious carbon deposit, and the most common reason for vehicle jitter is that the throttle is too dirty or the nozzle has too much carbon deposit. When there is too much carbon deposit in the engine, the gasoline sprayed by the cold start injector will be absorbed by the carbon deposit. 2. Engine cylinder missing: Engine cylinder missing mainly means that one or more cylinders of the engine are not working normally, indicating that the exhaust gas from the automobile is obviously intermittent, and the exhaust pipe is violently shaking, which can obviously feel the engine jitter, sometimes accompanied by abnormal noise. This is mostly related to the failure of ignition coil; 3. The engine combustible mixture is thin and thick, which leads to idling jitter after cold start. The lower the temperature, the more oil is needed for cold start and the more carbon is deposited, which will affect the success of cold start.
