Have you experienced rough idling o r engine hesitation due to a faulty purge control valve?

A malfunctioning purge valve can disrupt the air-fuel mixture, causing rough idling o r jerks during acceleration. Did your car behave this way before repair?

Yes, when the purge valve is stuck open, it allows excess fuel vapors into the intake manifold, leading to poor air-fuel mixture. This causes rough idling, uneven acceleration, and engine hesitation, particularly in traffic o r during gear shifts. Many owners confirmed that these symptoms disappeared after valve repair o r replacement.
