What should I do if Roewe 350 is not idling well?

Roewe 350 has serious idle jitter, so it is necessary to check whether the engine of the car is normal, especially whether the throttle valve and spark plug are used normally, whether there is carbon deposition and whether there is fault performance of excessive clearance. Idle speed is a working state of the car, which means that the engine is running in neutral. The idle speed of an engine with excellent working performance is generally 550~800 rpm. When there is something wrong with the idle speed of the car, the engine will make a sound. When the engine releases the accelerator pedal during operation, the engine will be at idle speed, and the idle speed cannot be adjusted up and down, which will cause wear and tear to the engine. The idle speed of the engine is called the idle speed of the engine, which can be adjusted by adjusting the throttle. Million car purchase subsidy
