Does A Bad Purge Valve Affect Gas Mileage?

Yes, a faulty purge valve can affect fuel economy. When the valve does not control fuel vapors correctly, the engine may receive an improper amount of vapor or unmetered air. Depending on the failure, this can contribute to rough idling, hard starting, reduced efficiency, or increased fuel consumption. However, a drop in gas mileage does not automatically mean the **purge valve** is bad. Other EVAP components, fuel-system problems, tire pressure, driving conditions, sensors, and engine issues can also affect fuel economy. The purge valve is part of the vehicle's evaporative emissions control system. It controls when stored fuel vapors move from the charcoal canister into the engine intake to be burned during combustion.
