How to solve the automatic flameout during the driving of Qichen?

First, check the carbon deposition of the throttle body when the engine is turned off during driving. Secondly, the resistance value of the crankshaft position sensor itself is abnormal, which leads to the disappearance of the crankshaft speed signal after the hot car, leading to the engine flameout. The gasoline pump itself fails, and the resistance changes after long-term work, which can not provide normal fuel pressure, leading to engine flameout; Ignition system failure, ignition module overheating can not work normally, ignition voltage is invalid, engine flameout; Abnormal throttle signal voltage and abnormal engine computer control will cause the vehicle to stall when driving; There is a phenomenon of virtual connection in the line, which leads to the occasional flameout of the engine. This kind of fault needs a comprehensive inspection.
