They didn't look that bad when I checked the comp. A little dark but not wet. they have about 5k on them so I'll pick up a new set on my way home. Didn't make sense to me that starting fluid didn't even get a spudder or make the plugs wet.

yah if you used starting fluid and it didnt even try to fire then something is off. what did you mean noid light on the sparkplug wire? i know theres noid lights for the injector and iac valve but never heard of one for spark. what is it?

I call it a noid light just cause does the same thing with the spark as with the injectors. Inline spark test light. I also have a wireless spark tester you just touch to a plug wire and it uses you as a ground to light up for fast diagnostics but I should use the technical term. Sorry
