A positive crankcase ventilation or PCV valve can cause an engine misfire, especially at idle and worse when the engine is cold. If the valve sticks in the open position it will act like a vacuum leak. If the valve sticks closed it can disturb the fuel air mixture. For far more information on PCV valves please see our Detailed Topic, Symptoms of a Bad PCV valve.
