Failure occurred after cleaning the throttle and idle motor.

This problem has occurred in my car before, and it is useless to clean it, and it is useless to just change the motor. It is recommended to change the throttle assembly directly, which is not expensive. The effect is definitely that I have never felt high or low. Idle at 900, the oil light is on. Check the oil pump pressure. The problem of turning on the headlights should be the generator. When the distributor or ignition coil works, it competes with the headlights. Check that the generator output is normal, which is 13.5. If there is something wrong with the generator, the oil pump light sometimes lights up. Go and have the car circuit repaired. Profession is much better than just fixing cars.
