What should I do if Geely pride 3000 doesn't turn down at idle speed?

As for the problem of high idle speed, the reason may be that the carbon deposit blocks the idle passage, causing the throttle valve or idle motor to be stuck or beyond its adjustment range, or that the throttle valve is stuck because of too much carbon deposit, which will cause the idle speed to rise after receiving oil. After cleaning the throttle, the idle speed of oil collection will increase, which has happened many times. This is because when cleaning the carbon deposit, the carbon deposit solution enters the throttle shaft, causing the throttle shaft and the valve body base to get stuck. It is also possible that the throttle valve cannot completely return to the initial position set by the manufacturer because it is not initialized after cleaning, and the throttle valve has a large opening, which leads to the phenomenon of high idle speed. It may also be caused by air leakage in the air intake system.

There is also the phenomenon of car jam you mentioned, which is also related to the excessive carbon deposition inside the engine.
