What should I do if the idle speed is high and it falls back slowly after the Fit washes the throttle?

Landlord: After cleaning the throttle valve, it is necessary to set the throttle valve. There are standard operation methods for cleaning. Generally, it should be brushing. It is best not to spray the throttle valve with cleaning agent, which will easily cause liquid to flow into the sensor. In addition, improper operation may lead to deviation of sensor values. In this case, I suggest you go to the service shop and check whether the data is normal with the detector.
