MSD Ignition Coil Plug Wire Replacement

[BALLSS]

If I were to use dielectric grease inside the coil wire boots, would it help prevent this stuff?

Dialectic grease should be used on both boot ends (inside) of plug & coil wires. Just put it inside the boots, not really on the terminal ends

Well I went and got some dielectric grease and gently applied it in the boots of the coil wire with a q tip then put it back on. I let it idle for about 15 minutes but once it warmed up, the service engine light came on along with the cooling fans which sounded awful for some reason like they were hitting stuff, and then the car started idling like crap so I shut it off. I guess I'll have to buy an OBDI scanner to hook up to it and see why the light is coming on and go from there

For your 94, you might want to consider downloading the free Sca9495 scanning/data logging software. You just need to pick up a cable.

If you go to look at dual capability OBD-1/OBD-2 scanners, I would recommend an Actron. They have a discontinued model on Amazon for about $70. Do not get an Innova or an Equus. The LT1 database is screwed up, and some models give a bogus list of seven codes, even if your PCM has no codes.

If you go with the Actron CP9185 scanner, you will need the CP9127 cable set also, about $30.
