- Remove resistor from spark plug.
- Resistor is about 3"-4" long - metal.
- At the end of the resistor where it connects to the spark plug wire, you'll see a small runner piece that can be folded down towards the resistor.
- Once that folds down, you should be able to simply unscrew the resistor from the plug wire. Loosen counter-clockwise. It's that simple.
Some may be a bit more stubborn. Steve Brotherton wrote about this a ways back - forget when - about a year or more ago.
