Can I drive without a purge valve?

Can A Car Run Without A Purge Valve? EVAP systems must have this valve, even though it is a small component. If you don’t have it, your engine will run very slowly and it will have a hard time working. In addition to the fuel to air mixture, other parts of your car may suffer from its high level of carbon dioxide.

What happens if purge valve is stuck closed?
