What is the problem of the Great Wall c20 flameout after striking a fire in the morning?

The cold car is easy to stall, and the idle speed is slightly unstable after the hot car is started. If it is an electronic throttle, there should be too much carbon in the throttle and it can be cleaned. If it's the throttle line, try cleaning the idle motor. If you step on the accelerator at the beginning, you can stabilize the engine. Once you release the accelerator pedal, you will shut down the engine. Another possibility is that the VVT solenoid valve is stuck, just check it and clean it up or change it (I met this kind of solenoid valve stuck once with the repairman).
