What is the idling jitter after cleaning the throttle?

Landlord: According to the above-mentioned vehicle maintenance phenomenon, combined with the vehicle condition and maintenance case, this situation belongs to the phenomenon of idle value setting. Because the vehicle has been used for a long time, the carbon deposit in the throttle valve is slowly increasing. At the same time, the computer is constantly fine-tuning the idle value (gradually opening more idle channels). Due to the limited opening of the idle channel, when it can no longer be opened, idle jitter and flameout will occur, but the vehicle will not be put into ECU after cleaning. So I suggest you go to the maintenance franchise store to set the idle speed value.
