i agree i went through everything to figure out what was wrong. tps, mass air sensor, cats, ground wires, spark plugs, fuel pressure, fuel pump, vaccum leaks, you name it i did it. Well after i was about to give up i decided to give it one last crank not knowing i left the o2 off. cranked right up. The car would rev up i could drive it. If i plug the o2 in now it just does what it did before. (my problems before)
