What's wrong with the high idle jitter noise of Sylphy?

The main reasons for the noise caused by idle jitter are: 1, too much carbon deposit in the throttle or nozzle, which leads to loud noise of the vehicle; 2. The spark plug is too dirty to work normally; 3. There is a fault in the high-voltage lead or ignition coil, resulting in a lot of noise. If the vehicle makes a lot of noise when idling, it is necessary to check the spark plug of the vehicle first to determine whether there are many impurities on its surface, which makes it unable to work normally. It is recommended to replace the spark plug in time. Then, clean up the carbon deposits in the engine, throttle and fuel nozzle of the vehicle, and replace the oil pad and other components again; If the phenomenon of vehicle idling jitter still exists after treatment, it is suggested that the owner should go to a professional garage in time and let professionals test and repair the fuel supply pressure and intake pressure sensor.
