On the Idle Speed of Adil

As for the problem of high idle speed during starting, the reason may be that the idle speed control device is stuck or beyond its adjustment range due to carbon deposition blocking the idle speed channel, or the throttle valve is stuck and cannot return to normal due to too much carbon deposition. Many times, this phenomenon will occur after cleaning the throttle. This is because when cleaning up the carbon deposit, the carbon deposit solution enters the throttle shaft, which leads to the blockage between the throttle shaft and the valve body base, and sometimes the throttle body needs to be replaced seriously. It is also possible that there is too much carbon deposit in the engine or there is something wrong with the quality of the oil, which leads to the recurrence of such a fault phenomenon in a short time after replacing the idle motor. You can check according to the above analysis.
