Sounds like cobra is misfiring

[Sprayed2v]

I know this thread is old but I have a question about the original Ops problem. My car is doing the same thing and the tuner found it to be misfire on cyl 2,5 and 7. He said at about 1500 it sputters all the way through 3k rpms. Mine didn't have this problem until I switched from tr6s to br7s. I'm wondering if that's my problem, or of my COP are shot. When changing the plugs I noticed cracks in the tops on the Coil. I have a 3.4, cammed, auto cobra I just finished putting back together and I'm only running 93 atm.

Old thread for reference.

Why not switch back to tr6's and see if the problem still exists? Might be time to to replace some coils, especially if they are cracked. Not taking advantage of the 3.4 with the right fuel, boost, and timing it must feel sluggish.
