Definitely replace the plug wire if its burnt or cracked. It will make it run like **** if its arching. I know this from personal experience. It'll feel like a 4 cylinder!! lol

Locktite on aluminum heads is a NO NO. Unless you don't want threads in your heads when you take out the bolts.

Well, I did leave the optispark holes uncovered when i did the delteq (oops) - i.e. i didnt cap the spark plug wire holes with anything. Could this have caused moisture, dirt etc. to get up in the opti?

just a thought

and is there anything bad about autozone optis? or should i just get one from Jason?

I wonder how hard it would be to remove an optispark from the top? lol - not so hard i'd imagine (with a Delteq and all)

thanks!

Is the car still running like crap? I had a problem with a O2 ground wire on the egine harness. My car ran like s*** right from the start and stumbled so hard i couldnt get it up over 35 mph all because of a o2 ground wire short in the engine harness.
