Re: Changed Spark Plugs 79 Camaro Now Misfires??

One thing I did find is that with the new 8mm wire that I just replaced is seated so close to the exhaust that it melted away some of the rubber boot! within 1 day! There is no metal exposed but other than needing to wrap my headers in some kind of insulation I really cant see a slightly melted boot being the problem. I did buy an ignition testing gauge (the one you hook up to the end of the wire to test for spark) but haven't tried that yet. But thinking logically about the things I changed, there shouldn't be too many things that could have gone wrong, I.E.

1. Engine Runs smooth
2. Change spark plugs from Champion to ACDelco gapped at .045
3. Engine slightly loping/misfiring at idle (barely noticeable)
4. Engine loping 90% throughout acceleration (noticeable)
5. Completely replaced melted distributor wire on cylinder 5
6. Nothing changed, hit the forums

Would it be impracticable to replace the whole set, or go through one by one with a new plug?

Thanks for all the help, crazy ass problem
