A vacuum leak from the PCV grommet vacuum leak can cause the Check Engine Light to illuminate. The molded rubber hose connections may crack and collapse, causing the vehicle to run roughly. A damaged PCV hose will require replacement.

    Check Engine Light was on and the engine ran very rough, particularly while idling.

    Repaired by Replacing the elbow-crankcase ventilation tube (Ford part number YL8Z-6767-AA) $9.

    However it took 2.5 shop labor hours to replace the part, which seemed a bit high.
