im having a little issues here....my gtp will act very funny. i will sometimes go WOT or under a decent amount of acceleration and it wll either downshift and seems like its falling on its face. the plugs have no marks of burns or anythign of that such.... it has codes for the EGR stuck open, The MAF low circuit, bank one lean, and it has a misfire code cyliner 6 but im sure thats from another instance and has nothign to do with it. I have cleaned the MAF with no improvements. if i unplug it it will want to die under any gas i give it so if im correct the MAF is fine.. i dont like seeing my gtp acting up like this mods are intake, DHP PCM, 3"downpipe catless, AL606s, 180 stat. any suggestions?
