"Swap the plug wires one at a time from the old cap to the new so you never cross the firing order. The Acty distributor sits at the mid-mounted engine, so work from the bed access."
Frequently Asked Questions
Should I replace the rotor at the same time?
Yes. The cap and rotor wear together - fit them as a pair for a clean ignition.
Does this generation need any programming?
Fit the cap and start the engine, nothing to reset.
How do I check my distributor cap?
Pop the cap off and look inside for cracks, thin black carbon tracks between terminals, or corroded and burned contacts. Any of those means replace it, and do the rotor at the same time.
