After cleaning the throttle, it will catch fire, and the car will not catch fire in a few days.

This phenomenon may be related to matching. After cleaning the throttle body, you need to use a diagnostic computer for initialization settings, and then you can use it normally after re-matching. Secondly, it may be the fault of the gasoline pump, and the poor work of the oil pump will also lead to the difficulty in starting the vehicle. I suggest you observe for two days. If it is caused by improper matching, it may be better after two days.
