What is the reason for the low idle speed of the car?

1, throttle oil storage and throttle carbon deposit, air inlet is too dirty;

2. The spark plugs caused by individual spark plug failures are too weak;

3. Common problems include idle speed control valve failure, poor atomization or blockage of injector, and oil viscosity change. With the extension of the service life of the car, the air inlet of the car will be blocked, and there will be carbon or engine oil on the throttle, resulting in unstable or even low idle speed. The throttle affects the air intake due to carbon deposition, and the idle speed will also be low when the car starts. It is suggested that the owner clean the throttle and air intake of the car to avoid abnormal idling of the car.
