Order of inspection
P0496 Evaporative Emission System High Purge Flow Low
The P0496 code means more vapor from the canister is getting into the engine than the computer expects, almost always because a purge valve is stuck open. It causes hard starting after you fill the tank. It is a low severity code and you can keep driving.
