Throttle has been cleaned. Idle speed is high.

Reasons for high idling speed of automobile electronic throttle cleaning: 1. Because there will be impurities in the intake process for a long time, these impurities will accumulate at the throttle for a long time, and then more and more carbon will be deposited; 2. The throttle will be resisted for a long time when reciprocating, so the engine computer will adjust the position of the throttle. That is to say, taking the position of carbon deposition as the body is equivalent to that the throttle valve is not at all but close to the position of carbon deposition; 3. After the vehicle cleans the intake valve, the flap still moves in the original formation, which means that it is not in place, but the difference is that the carbon deposit is cleaned; 4, so the air intake will be a little more than usual. This will lead to high idle speed. In this case, you need to do computer programming. If you don't do it, the engine computer will take a long time to adjust and recover.
