Engine Affected: 1.8L V6


Vehicles with a V6 engine may develop an engine misfire under load (acceleration). This can be caused by a valve cover gasket leaking oil into a spark plug well, shorting the spark plug to the cylinder head. To repair this concern, the valve cover needs to be resealed and the spark plugs and wires should be replaced.

    No solution yet, but I have oil leaking into 2 of the spark plug wells and drenching the spark plugs and this is leading to problems with acceleration
