What is the reason for the engine jitter of Dongfeng Jingyi s50?

Reason for engine jitter of Dongfeng Jingyi s50: 1, slight jitter is normal, and serious jitter needs to be checked;

2. The most common cause of automobile jitter is that the throttle valve is too dirty or the fuel injector has too much carbon deposit;

3. 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, the gasoline absorbed by carbon deposits will only be saturated;

It is easy to get into the car. After getting on the bus, the gasoline adsorbed on the carbon deposit will be sucked into the cylinder by the vacuum suction of the engine for combustion, which will make the mixture rich, and the combustible mixture of the engine will be diluted and concentrated, resulting in idling jitter after cold start.
