After fueling car ,the car will run ruff and cut out.just sometimes
The purge valve in the EVAP system my be leaking.
When this happens, as the vehicle is being refueled, gas vapors are forced into the engine which creates a flooded condition. This will cause the vehicle run rough when it’s restarted until the flooded condition clears. And sometimes it might cause the engine to stall.
To determine if this is what’s happening, the next time you refuel the vehicle, hold the gas pedal to the floor when you go to start the engine.
If the engine starts without running rough/stalling, that’s what’s happening.
