man thats alot of information thanks!!! ya its actually not giving me any codes i just know its code 43 cuz i had it a while back and its the same exact shit thats happening. i have lowered my fuel pressure and have not yet had a problem. im going to get another chip done that has the o2 enabled that way i can at least have a way to know for sure if im running rich or lean. pretty sure its runinng rich i can smell gas on start up but with no o2 sensor it might run rich anyways at idle.
