How to deal with the jitter of gs4 Chuanqi engine?

Possible causes and solutions of engine jitter: 1. The most common cause of vehicle jitter caused by serious engine carbon deposition is that the throttle valve is too dirty or the injector has too much carbon deposition;

2. When there is too much carbon deposit in the engine, the gasoline sprayed by the fuel injection head will be absorbed by the carbon deposit during cold start, which leads to too thin mixture during cold start and difficult start. In this case, only when the gasoline adsorbed by carbon deposits is saturated, it is easy to run into the car. After running into the car, the gasoline adsorbed on carbon deposits will be sucked into the cylinder by the vacuum suction of the engine for combustion, which will thicken the mixture and dilute the combustible mixture of the engine, resulting in idling jitter after cold start.

3. The lower the temperature, the more oil is needed for cold start, and the existence of carbon deposit will affect the smooth start.

4. Solution: Clean the oil circuit and check whether there is carbon deposit in the idle motor, which should be cleaned.
