95 lt1 breaking up at WOT
well today, i was playing around out on the streets, and i have been having this problem with when i reach around 5000 -5500 rpms, she breaks up dumping black smoke from the exhaust. it doesnt do it when the engine is cold or sitts for about 15 min. so i reset the tps yesterday and no change changed the opti, and o2s are brand new. plugs look fine wries are new also, fuel psi is reading around 40-43 at idle.
so im lost on this. any one know what this could be.
thanks

Have had a weak MSD coil do this once. Replaced it with a new stocker and no more problems.
