LowSS

Developed a miss at idle and a ticking on my 2000 SS and it steadily got worse over the weekend. Turned out to be a plug wire had a tear in it and was arcing to the egr/header connection. Fixed that, fired the car up and i'm still getting a missfire with a louder ticking, after an hour or so I found that the wire harness running to coilpack on the same cylinder was arcing from the pink wire to the heat insulation below. The wire had a small tear in it, wrapped with electrical tape till I can find a better way to fix it and that took care of things. Seems to have taken care of my ticking also. Hope this can help someone with similar problems.

Good fix! Plugs/wires should always be the first thing to check. And you were on your game to catch the shorted wire.

I've swapped wires/plugs at least 5 times hoping to fix the same problem every time, but it's never worked. I REALLY don't want to buy a new set of coil packs, but I guess I have no choice at this point.

I had the same problem but my cause was a spark plug coming unthreaded a little bit. The tick was very loud. I thought it was an exhaust leak.
