What happened when the pipe of Angkor Serra throttle valve was unplugged and then turned off?

The pipe is reconnected and everything is fine.

Connect all the air pipes and the vehicle will be normal. Without intake air flow data, the engine will stall. Drive to the on gear, press the accelerator pedal with a brick, and drive without starting the car. It is recommended to disassemble and clean. The cleaning agent entering the manifold has an influence on the concentration of mixed gas, so it is difficult to start at first. This stall situation is too dangerous, so you must go to the 4S shop as soon as possible to check and solve it. If not, you can ask for a transfer. This sudden flameout poses a safety hazard to drivers and passengers.
