Can I drive with a bad purge valve?
It’s certainly possible to drive with a broken purge valve, but we don’t recommend it. The longer you drive with a bad valve, the more risk you run of damaging the vehicle’s EVAP system and other parts. There’s also the possibility of wasting fuel and pumping out more emissions than is necessary.
