The van caught fire and couldn't lift the throttle. What happened?

1. If there is nothing wrong with the air filter, check whether 90 # oil is used. Secondly, if this happens in 93#, check the heat dissipation. If there is no problem with heat dissipation, check the valve closure of the engine. If the valve is not fully closed or the ignition is turned off, these will also cause the car to be weak.

2. Have the throttle, fuel injector and three-way catalytic converter been cleaned? The normal cleaning cycle should be about 20 thousand kilometers, and the car should be washed two or three times when it travels more than 60 thousand kilometers. So I suggest cleaning it. Also check whether the high-voltage line works normally and whether there is a fire break, which may cause the single cylinder to work badly. In addition, check whether the clutch slips. If the clutch slips, the engine will lose some output power, in severe cases.
