What should I do if the imported hacker lights up after washing the accelerator?

The most important thing is to look at the fault code. Generally, the unstable idle speed after clearing the throttle may be caused by the entrance of cleaning agent when clearing the head before the idle motor, which leads to the inflexible axial movement of the motor and the unsmooth idle speed adjustment. The car computer detects data to control the idle motor, but when controlling the motor, it is found that the speed is still abnormal and a fault light appears.
