SPARK PLUG WIRE INSPECTION

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:
- Tearing

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.
