Just a lil' info to keep the ole SC purring like it should... We all should be doing this BEFORE we try to go faster in any car...

Then maybe we'll get the MPG, dyno and 0 - 60 times we are looking for

Merry christmas all!!

I was reading the article and found this:

The cap and rotor should be checked every 20,000 miles and replaced if excessive wear and tear.

Is this true for All SC's?? What should we look for?

Good question... I changed my plugs, wires, caps because my car was running a lil' sluggish. I did a visual inspect of the caps but I really did not see any cracks or anything in the cap. Maybe a smarter member could explain what to really look for .

Don't know that I'm any smarter than anyone else, but I've seen a few things I'll pass along. You can check the integrity of your ignition (cap & plug wires).

1. On a dark night, start the engine, raise your hood (if you have a light take it out) and look closely around the cap & along the plug wires for small sparks. These sparks can jump from wire to metal or wire-to-wire. In either case, that wire's insulation has broken down and needs replaced. Very likely, all the wires are the same age, so you'd be smart to replace the set.

2. Sparks from the cap can be caused from "carbon tracking", usually a crack in the cap traps carbon particles that provide a current path to the best ground. Same situation, replace it.

I usually replace the cap and rotors around the same time as I change out my spark plug wires.

As for the insulation breaking time. You're better off using a voltmeter and measuring the resistance of the plug wires.
