Hi all, I have an 88 gt that I am trying to set up for an entire top end soon to come. I was advised that in order to do this I had to switch to mass air. I work at a part store so acquiring the correct computer and mass air flow sensor was easy enough. I picked up a wire harness from ebay with a good set of directions and wired it in. The stang runs great but it is having idle problems and I am confused about what I should do. It only runs if I have my foot on the gas, when I come to a stop it quits. Any and all suggestions are welcome! Thanks in advance.

did you change injectors? What is your Maf calibrated for? What computer do you have?
