After he fixed the o2 sensor problem everything was alll good. I think this is the case with my truck being that i started to experience shifting problems after I installed the offroad headers w/o cats. Also I finally realized why my truck cuts out mid burnout or heavy acceleration which is due to torque management so i think you guys can bypass that too right?
