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?
