How to Improve the Electronic Throttle and Idle Speed of Jiangzhun He Yue?

When the vehicle is driving normally, the throttle is lost, the gear is placed in a narrow gear, and the engine speed rises instead of falling. Sometimes, when you wait for a red light or stop for several years, the engine will not turn off. Under normal circumstances, it should be idling, but at this time the engine speed reaches 2000 r/min. If the vehicle is turned off and restarted or the accelerator pedal is pressed, the vehicle will return to normal. This doesn't always happen, only occasionally. With the increase of mileage, the time interval will be shorter and shorter.

Fault analysis: the vehicle enters the store for maintenance for the first time, and it is inspected routinely. No problems were found, and the data flow was normal. Therefore, when the vehicle is driving at a red light in the downtown area, there is a fault phenomenon. When the vehicle is idling, the engine speed slowly rises to about 2000 r/min, and the sound of engine refueling can be clearly heard, but no one steps on the accelerator at this time, because it is in the downtown area and the vehicle is in the middle of the road, which is inconvenient.
