After the Chery QQ flameout, the idle motor rang.

The reasons for the noise generated by the stalled idle motor are:

1, the engine, throttle and spark plug have more carbon deposits;

2. The air filter element becomes dirty;

3. The car oil is dirty or the quality is unqualified;

4. The transmission shaft is short of oil for ten bytes, resulting in wear and damage;

5. The engine pad is damaged; 6. Abnormal cylinder pressure.
