Spark plug wire integrity is vital for proper engine operation. A thorough inspection will be necessary to accurately identify conditions that may affect engine operation. Inspect for the following conditions:

• | Correct routing of the spark plug wires--Incorrect routing may cause cross-firing.

• | Any signs of cracks or splits in the wires.

• | Inspect each boot for the following conditions:

If corrosion, carbon tracking or arcing are indicated on a spark plug wire boot or on a terminal, replace the wire and the component connected to the wire.
