Wuling Wangxing engine always shuts down as if it were blocked by a valve when driving.

Hello! The fault is poor acceleration of the engine. Please check: 1. Whether the throttle body, idle motor, fuel injector and fuel pressure regulator are dirty, blocked or stuck needs cleaning. Second, check whether the spark plug, cylinder line and ignition coil are aging, burning, leaking, damaged and need to be replaced. And whether the cylinder line socket of the ignition coil is oxidized and rusted, resulting in weak ignition ability. Third, check whether the gasoline filter is dirty, blocked and needs to be replaced. Test whether the pump oil pressure of the gasoline pump is too low? Fourth, check whether the engine intake pipe and valve are seriously carbon-deposited. Check whether the exhaust pipe three-way catalyst is blocked and whether the air filter element is dirty and blocked. I hope I can help you. If there is something wrong with your car, ask the car mechanic. 4S shop professional technician, 10 minutes to solve.
