What caused the flameout of Shanghai Yinglun SC7 15 after startup?

There is something wrong with idle speed. You can try this. Step on the accelerator a little when you start, will it not turn off? If not, there is something wrong with the throttle. Many cars are a little unstable at first because the throttle is too dirty. Being too dirty for a long time will cause the throttle to stall. You can go to the maintenance point to do a throttle maintenance first, and then see if the exhaust is normal.
