falls on face when put in drive when I put my truck into any gear and try to get on it it just boggs real bad and wont even spin the tries and it sounds horrible .the motor runs okay it has some backfires when cold and sometimes when idling warm but revs up fine .the only code is for o2 sensors .the motor is an 04 gto ls1 with the stock 4l60e trans with all electronics intact with a np241 transfer case .any help would be apreciated

Need to slap a scanner on it and give us a data log to crunch on.. RPM, IAT, ECT, MAF, MAP, O2's and timing for starters. That alone would probably give us enough to tell you what's out of wack

The O2's are probably telling you the truth then if it's falling on it's face like that. Check those MAF, MAP, IAT (if not MAF integrated) and ECT sensors. Also for any major vac leaks. Anything else modified on the engine or is it completely stock otherwise? Know anyone who has HPtuners, EFI, TECH-II scanner in your area? A scan tool is really your best bet to knowing whats going on.
