The idle speed of Xinbaojun rs3 is unstable.

The idle speed of Xinbaojun rs3 is unstable for the following reasons:

1, air filter. The blockage and pollution of air filter will affect the amount of normal air entering the engine, resulting in unstable idle speed. The solution is to replace the air filter.

2. Fuel system. Blocked fuel filter, oil pump failure and air leakage in intake pipe may all lead to unstable idle speed. At this time, you can clean the fuel filter or replace the oil pump.

3. Ignition system. If the spark plug is burned or aged, it will affect the normal ignition and lead to unstable idle speed. The solution is to replace the ignition system accessories.

4. Air intake system. Even minor faults of intake valve, throttle valve, intake pipe, air flow meter and other components will cause unstable idle speed. Corresponding parts need to be adjusted or replaced.
