What is the high rotating speed of Hong Guang Bronchial Switch in Wuling?

First of all, you need a computer to detect whether the engine electronic control system is faulty. If there is a fault, it must be eliminated first. Check the air intake and exhaust system for air leakage. Finally, we need to clean the throttle, then match the throttle, and then test drive. If it doesn't work, we need to do computer programming.

Other reasons

Because there will be impurities in the intake process, these impurities will accumulate at the throttle for a long time, and then more and more carbon will be deposited.

When the throttle valve reciprocates, it will be resisted. If this situation persists for a long time, the engine computer will adjust the position of the accelerator pedal. That is to say, the position of carbon deposition is regarded as the ontology, that is to say, the throttle valve is not at all but near the position of carbon deposition.

After the vehicle cleaned the intake valve, the flap still moved in the original formation, which showed that it was not in place, but the carbon deposit was cleaned. So the air intake will be a little more than usual. This will lead to high idle speed.

In this case, computer programming is required. If you don't do it, the engine computer will take a long time to adjust and recover.
