SPARK PLUG WIRE INSPECTION

1. Correct routing of the spark plug wires.

Incorrect routing may cause cross-firing.

2. Any signs of cracks or splits in the wires.
3. Inspect each boot for the following conditions:

-

Tearing

-

Piercing

Corroded terminal

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