What is the reason for the car throttle ringing?

The causes of the car throttle ringing are: 1, the oil pressure is unstable, so check the oil pressure;

2, engine carbon deposition, cleaning the throttle, cleaning the nozzle;

3, ignition system problems, check the ignition coil and spark plug;

4, you can try to clean the throttle, because the throttle of the cold car is easy to accumulate carbon in summer and autumn, and it is easy to cause idle noise if the throttle is not cleaned for a long time;

5. The engine idling sound is too loud (the sound when the engine door is open), so listen carefully to the sound source. Check whether the exhaust pipe is broken.
