Cool car of Wuling Hongtu is fine, but the hot car can't add gas. What happened?

1, check the oxygen sensor. If 90 # gasoline is often added, it is easy to cause oxygen sensors. Pull it out and test it. If the acceleration is normal, it is damaged and it is better to replace it.

2

Check water temperature sensor, air pressure sensor, idle motor and throttle position sensor.

3,

Check whether the three-way catalyst is blocked.

4,

Clean the fuel injectors and check the ignition system.

If not, please ask questions, if satisfied, please adopt, thank you.
