My truck has about 130K. After checking around its just the drivers side bank thats running lean. I ordered an O2 sensor from summit should be here in the morning. Once I wrench that off and replace it I'll clean the MAF and see how she runs then.

Yes the exhaust smells a bit under load/accelleration.

Also on the chance that a coil has gone bad I ordered 8 Accel Super coils, only because I could talk them down to $15 a coil because of a misprint on thier webpage

The problem didn't start because of the exhaust because it ran fine when I bought it and the exhaust was already on it. I'm still looking around for a Ballance Pipe... I'd need an X-pipe but because of the tansfer case the 2 exhaust pipes are run so close together I need a very tight/narrow/close X pipe and I just haven't found one yet(haven't looked real hard though)
