hey man i saw that you had done more than a few maf conversions using the pigtail and the stock wiring harnesses. i was wondering if you could help me with a problem i'm having with mine. i have an 88 and i bought a computer, sensor and pigtail i wired it up with the exception of the fuel pump monitor and the vehicle speed sensors simply because i was told that it wouldn't create a problem. however now my mustang runs super rich until it warms up then it runs fine. have you ever heard of anything like this and could the sensors that i havn't hooked up yet be the problem, any advice would be very much appreciated, once again it's an 88 5.0 thanks!!
