Can you do a Key On Engine Off test?

I had a similiar condition when one of my O2's went out, but I did get a code and a CEL

Check engine light is on after my xpipe and exhaust install. The misfire was going on before that though...

Your CEL should not come on due to exhaust mods. Check and see what code it is

Unless somebody forgot to plug the O2 sensors back up.

Update: I went ahead and replaced the TFI module myself since I knew it could be the problem and that it needed replacing anyway. When I replaced it, the car would turn over but no spark... Bad new module...Tried old one and it cranked right up. Mark Knight swapped it out for me and it worked. However it didn't fix the sputter. I decided to take it to my friend Sean and let him tinker with it. He ran his scan tool on the car and found that the driver side o2 is more than likely unplugged(haven't looked yet). The sputter was to blame on the #4 plug being closed all the way. Runs smoother than it ever has now! It's never ran this good I am so relieved...On top of that he didn't charge me a penny! I told him I would pay for his beer one night when we go out or something.l..Anyway project ice ice baby is rollin smooth, a/c is cold, water pump is on, no problems whatsoever!
