Ok, got the car running, it has NO codes..... When I take off from a start all is good.. If I take off with it matted, it wants to die out and the SES light comes on then goes off... What could this be, bad plugs?? My TPS is set at .58 right now...

 

sounds to me as if your having a drop in fuel pressure. standard dieing gm fuel pump is my best guess. check your fuel pressure at the test port on your injector rail. test it at a load (foot held on brake while giving it as much gas as you can before the tires brake lose). If you notice a drop in fuel pressure you are seeing a dead pump. or possibly a plugged fuel filter ,but unlikely in this case.
