Installing throttle cleaning

Regarding the problem of excessive idle speed after receiving oil, the reasons may be that the carbon deposit blocks the idle speed passage, which causes the throttle or idle motor to be stuck or beyond its adjustment range, or the throttle cannot return due to excessive carbon deposit, which will lead to the increase of idle speed after receiving oil. Many times, 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, which causes the throttle shaft and the valve base to get stuck. In severe cases, it is sometimes necessary to replace the throttle body or idle motor. In addition, after cleaning the throttle, the throttle should be initialized. If you have cleaned in an ordinary repair shop, I suggest you go to a regular 4S shop to check it out.
