What causes the throttle to ring after the fire goes out?

There may be something wrong with the engine control module. It is recommended to go to the repair shop for inspection. If the general control module is faulty, it can be repaired around 300 yuan.

It is also possible that a relay did not release, so that the engine control unit continued to work and kept idling, so the oil pump would not stop and the throttle would jump. So the power went out overnight.
