What happened to the high starting speed of the hot car after clearing the throttle?

Normal, because the throttle was pushed away because of dirt before the throttle was cleared, but the computer ECU has adaptive function, so the current position is set to the throttle idle opening! ! (For example, the original idle speed was 3, but it was 3 before the car started because of dirt, and it became 6 after the car started.) But because the dirt was removed after you cleaned the throttle, the computer couldn't adapt to the fact that the throttle was still 6 before, but because you cleaned the throttle, the dirt of 3 was removed, so the throttle really turned on 6! ! (Only applicable to vehicles with electronic throttle! )

Solution: let the car sit for a while and step on the gas pedal! !

If not, disconnect the battery cathode 15 seconds! ! But remember to adjust the clock time! ! )
