Random Misfires on Cammed Trans Am
Damn O2 sensors...my car ran fine pre-tune and then post tune it revealed a bad O2. 50 bucks later it runs fine.
Glad you figured it out! Enjoy the car.
I also wouldn't blame the seller if it ran fine for 400 miles, sometimes crap like that happens. O2 sensors wear out.

Even if I get it retuned at pcmforless or Tick performance would that help my missfire or oil consumption if you see the engine at idle you can notice a small missfire just how seeing it idle but you cant feel it when driving
Been having the same problem as you, car tries to die randomly either cruising or at a stop. I have the p0121, p1133 and p1153 codes popped up after my tuner, its hard to keep up with the car while in traffic because it randomly wants to die, did you completely solve your problems with the 02 sensor replacement? I changed mines for some NGK about 3-4 years ago but they're relatively new since I've only put about 6000 miles on the car since 2006.
