When the temperature of the car is high, it is not easy to ignite and it is easy to stall. Why?

This situation belongs to the hot car is difficult to start, the possible reasons are:

1, there is too much carbon deposit, and a large amount of carbon deposit will adsorb gasoline, resulting in a short-term lean mixture.

2. The oil nozzle drips oil. After the engine is turned off, the nozzle is not tightly sealed, and it is difficult to get into the car because it is immersed in the cylinder.

3. Insufficient fuel pressure is mainly caused by the failure of oil pump and fuel pressure valve.

4. The water temperature sensor and the intake pressure sensor fail, resulting in wrong sensing signals, resulting in the mixture being too rich or too thin.

5. Due to the failure of the high voltage package, the resistance value changes and the secondary voltage is too low, which makes parking difficult.

6, oxygen sensor failure, can't correct too much fuel injection, resulting in the mixture is too rich.
