Fuel Economy: The purge valve is part of the EVAP Evaporative Emission Control system, which manages the release of fuel vapors from the gas tank. If the valve is malfunctioning, it can cause fuel vapors to be improperly recirculated, leading to rough running conditions, hesitation, and inefficient fuel use.
Engine Performance: A stuck purge valve can cause hesitation, especially during acceleration, as the engine’s air-fuel mixture gets disrupted.
