Problem Reported: Oil in Spark Plug Tubes May Cause Misfire
November 23, 2010, 10:49 AM

On the V-6 engine, oil in the spark plug tubes can cause a misfire. Resealing the tubes as part of replacement of the valve cover gasket and replacing the spark plug wires will commonly repair this issue. On newer models the misfire can result in illumination of the Check Engine Light.
