What should Toyota do if the idling speed of cleaning accelerator is high?

After cleaning the throttle, the idle speed is high and normal, and the idle speed is low during operation. This is because the trip computer has the memory function of throttle opening. After the throttle valve is cleaned, the carbon deposit is removed. If the throttle valve keeps its original opening, the idle speed will be high.

After running a lap, the driving computer will constantly adjust according to each sensor, the throttle opening will drop and the idle speed will return to normal.
