What happened after Mitsubishi wing beat wash throttle turned to idle speed?

Regarding your question, after cleaning the throttle valve, the idle speed of oil collection will increase. It may be that the carbon deposit solution enters the throttle shaft when cleaning the carbon deposit, which leads to the blockage between the throttle shaft and the valve body base; It is also possible that the throttle is not initialized after cleaning, the throttle cannot completely return to the initial position set by the manufacturer, and the throttle opening is large, resulting in the phenomenon of high idle speed. I hope my answer is helpful to you.
