Spark Plug Wires Not Operating Properly

1. Inspect the routing of the wires. Improper routing can cause crossfiring.
2. Inspect each wire for any signs of cracks or splits in the wire.
3. Inspect each boot for the following conditions:
- Tearing
- Piercing
- Arc through
- Carbon Tracking

If the boot needs to be replaced, replace the complete spark plug wire.
