I have possibly a very stupid question. If i had a computer that had a chip in it for a B or D series would it still run an F? My car will start and idle and you can slowly give it throttle but it still stumbles. If you hit the throttle quickly it completely cuts out and just wont run. I put my buddys chipped f series computer in it and runs pretty good. I was thinking my air/fuel ratios were way off or something. Any thoughts are greatly appreciated.
