ISSUE
Some vehicles may exhibit an engine misfire or rough running condition. The Malfunction Indicator Lamp (MIL) may be illuminated with one or more mis-fire Diagnostic Trouble Codes (DTCs) stored. This could be caused by water entering the
spark plug well area of the engine. This may occur after the front of the vehicle or engine compartment is exposed to an abnormal amount of water. During this condition, water could pass through the protective convolute on the engine wire harness and eventually drain into the
spark plug wells.
ACTION
Remove a small section of convolute from the effected Ignition
Coil wire harness allowing any water that may accumulate to drain away from the
spark plug wells in the engine. Refer to the following Service Procedure for details.
