What's the matter with Mitsubishi Wingbeat stepping on the brakes or clutching?

Hello, it is possible that the throttle is stuck or out of its adjustment range due to carbon deposit blocking the idle channel, or the throttle shaft or idle motor is stuck and cannot return due to too much carbon deposit, which will lead to the idle speed rising after receiving oil. Sometimes, after cleaning the throttle, the idle speed of oil collection will rise. This is because when cleaning the carbon deposit, the carbon deposit solution enters the throttle shaft, causing the blockage between the throttle shaft and the valve body base. I suggest you check it from this aspect.
