I have a 96 z28 with an lt1 and it is miss firing i started doing it past 5000 rpms but now its missing all the time and idles really rough. IT has an msd coil and billet msd optispark, and msd plug wires any help appreciated!!!! come on LT1 pros

 

Make sure all your wires are on the spark plugs. I had the same problem and only turned out to be a wire popped off the plugs. Then again it could be a number of things.

 

i checked the wires none are burned and they are all burned , what color should plugs be?

 

i had a problem with my car randomly started popping, driving it hoe from where it started this it started to misfire real bad, ended up being an 02 sensor but id check everything, pull a plug take a look. Check fuel pressure. I also had a lower rpm misfire problem once which consisted of my opti arcing off in the cap. Missfires are always a broad subject kind of sucks, need to just look everything over real well.
