Need Help Burning Very RICH!!!!
I have a 91 GT w/ an 8 psi blower 30lb injectors and a 255 fuel pump. My car burns so rich at times it diesand there is a strong fuel smell. I dont have a fuel pressure gauge but know its rich. It all started when I have a new tranny put in. As soon as I picked the car up the MAF sensor went out and I got a new one and it ran ok for a few days. Could my fuel pressure regulator be out? I am just lost and need help, Thanks
P.S. By the way I am getting about 120 miles to a tank!!! |

Well first of all a fuel pressure gauge is a must with any modded motor for sure with a s\c motor if you dont know what your pressure is it is just a guessing game. it could be a bunch of things. First I would put a gauge on that thing for piece of mind.

What I'd like to know is how are you controlling the tune? FMU? PMS? Do you have a adjustable fuel pressure regulator on the car? You need a fuel pressure gauge.
