More than 60,000 kilometers of cleaning, before 800 rpm idle, now 1000 rpm is how to return a responsibility?

Let me tell you something. The reason may be that the idle speed control device is stuck or out of its adjustment range because of the carbon deposit blocking the idle speed passage, or the throttle valve is stuck and cannot return because of too much carbon deposit, which will cause the idle speed to rise after receiving oil. In many cases, after cleaning the throttle, the idle speed of oil collection will increase. 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. High fuel consumption should also be related to this problem. I suggest you check the carbon deposit inside the throttle and engine, and check the engine computer at the same time, and be sure to initialize it after cleaning.
