Uy 125 low idle speed after cleaning the throttle.

It has nothing to do with cleaning the throttle.

1 Spark plug is not working well, 2 vacuum tube leaks, 3 high-voltage line leaks, 4PCV valve is blocked, 5 throttle position sensor fails, 6 idle stepper motor fails, 7 idle control valve fails, and 8 throttle opening is abnormal.

Because the idle speed is too low, the spark plugs caused by individual spark plug failures are too weak. With the extension of service time, carbon deposition will also occur in automobile spark plugs. When carbon deposition is serious, the spark plugs on individual cylinders will be weak, which will affect the performance of the vehicle and lead to the phenomenon of low idle speed of the vehicle. It is recommended to clean or replace the spark plug in time.
