Isuzu Rodeo Oil in Spark Plug Tubes May Cause Misfire

(16 reports)

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.

Oil leaked into spark plug holes and shorted out the coil wires and cause a misfire in the right bank. This also caused the cat's to go bad and the 02 sensors had to be replaced! -

My check engine light came on, so i took it to Auto Zone. They ran a diagnostic and said it was the 6th cylinder misfire. So my husband and father in law took the spark plug out and there was oil on it. -
