The engine of mini-car 465 suddenly shuts down at idle speed, and occasionally it can't afford to refuel.

Hello! The mini-car suddenly idled and turned off. There is no money to refuel occasionally. Please check whether the throttle body, idle motor and fuel nozzle are dirty, blocked and stuck. Need cleaning. Check whether the fuel injector and throttle body line plug are in good contact. Second, check whether the gasoline filter is dirty or blocked. Need replacement. Check whether the pump pressure of the gasoline pump is insufficient and whether the check valve of the oil pump is depressurized. Third, check whether the spark plug, cylinder line and ignition coil are aging, damaged, burned and leaked. Need replacement. Fourth, finally, check whether the positive and negative connections of the battery are in poor contact. Fifth, also check whether the crankshaft position sensor plug is in poor contact? 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.
