If so take them out and replace with a resistor plug.

I like to diagnose from cheap to expensive.

I hate Bosch, Champion, Denso, and NGK. I know some people live by those plugs but i have never had luck with them. This thing has only got 23000 on it, never beaten original tires (which blow by the way they are so damn hard and slick). It still has the OEM Delcos in it which are as clean looking as the day it left the factory. Think I found the problem, just waiting on plenum gaskets so i can put it back together. Think it is my fault, I didnt realize when i pulled the upper to do injectors i had some coolant get down in the #8 spark plug well. I think is was causing a high moister issue and i think the spark was jumping through the boot. So I dried it out checked plug gaps. (customer doesn't want to replace them yet) and we have a good set of take off LT5 wires im gonna snag a #8 wire. (Maybe pray to the car gods) I'll let you all know how it turns out in a few days.
