Range rover throttle

The engine has a serious carbon deposit, and the most common reason for car jitter is that the throttle valve is too dirty or the injector has too much carbon deposit.

A flameout means that the engine is turned off. The reason may be that there is too much carbon deposit in the engine, and 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.
