What should Buick Lu Zun do after washing the accelerator and idling at high speed?

Lu Zun has a common problem in washing the accelerator. When you are driving on the road, put the gear in first and second gear, and don't drive with the air valve open. Two or three times should be fine, or go to the 4S store and reset the data with a computer tester. The idle speed is high because the computer host is still giving oxygen according to the position where the throttle is not cleaned, so the idle speed is high.
