Alright, it's a 95 z28 with hooker LT's, MSD Opti, MSD wires, and new plugs. I have driven the car a good 3000km after I routed the spark plug wires properly (was getting miss with it warm - cooked a wire), with no issues. A couple of days ago I started getting a miss again, I am wondering if my coil is on the way out? I can't see it being a plug wire this time because I have driven the car so much lately with no issues, usually a plug wire will burn fairly early.

Any suggestions?

 

Bad assumption that a plug wire always burns early. Since the symptom is the same, recheck your spark plug wires. Easily done in the dark with the engine running; look for the "light show".

 

x2 Its happened to me before, never rule anything out

 

Well fired the car up a couple nights ago in my garage, and let it warm up for a good 15minutes, until I could hear the odd pop come out of the exhaust. I looked under the hood and couldn't see any arcing whatsover, but could hear a pop every 10 seconds or so.

Any other ideas? I just yanked the diff out so I could install my moser 12 bolt, so I will have a couple down days with the car anyways.

 

I have hookers and I hadn't moved the bundle of wires that has foil on them running down the inner fender on the right side. Then started having problems when it warmed up (went into closed loop) ran real S@#TY.

Tested the O2's and found the bundle burned through even with the foil inplace.

If you unplug one of the O2s and it drives good, suggest you look into it.
