    Q:
    How does the PCV valve maintain idle quality for the 1985 Pontiac Fiero? Posted by Customer
    A:
    The PCV valve maintains idle quality by restricting flow when intake manifold vacuum is high and allowing excessive blow-by gases to backflow into the air cleaner for combustion in abnormal conditions.

    Q:
    How do you check the PCV valve on the 1993 Pontiac Grand Prix? Posted by Customer
    A:
    Locate the PCV valve in the valve cover or intake manifold behind the throttle body on 3.4L engines. While the engine is idling at normal operating temperature, remove the valve from its rubber grommet. Cover the valve's end with your finger and check for vacuum. If there's no vacuum, inspect for blockages in the hose, manifold port, or the valve itself. Replace any obstructed or deteriorated hoses. Turn off the engine, shake the PCV valve, and listen for a rattle. If there's no rattle, replace it.
