i used search but couldnt find anyone who seemed to have the same thing goin on. but i hooked my safc up in my car about 2 days ago. car ran fine before, after installing the MAF just didnt work. it was almost like while the safc was connected the MAF just didnt exist. idle dropped from 1000 to 450ish. bypass the safc, car again runs fine. i thought it was the safc so i tried a friends, whos works fine, same problem, MAF falls off the face of the earth. does anyone know if maybe i need a different wireing diagram? maybe someones had the same problem and knows what i need to do?

i would double check your wiring. When you unplug the safc thats when your car should run bad. I bet you have a wire switched or something.

well both safc's have been wired in twice. once by me, and once by revolutions performance. we tried 2 different ecu's, and even two different MAF sensors by using my friends 88 turbo, all with the same result, car barely wants to run with safc plugged in, but completely comes back to life with it bypassed.

did you do the initial startup settings? It should be set to karmen sensor and the arrow pointing up and to the right
