I'd like to get a few things determined about the 3.8 NA's. I know for a fact that all 89-90 3.8 NA's have a MAP sensor, and all 91-97 3.8's have a MAF sensor. Now the question is -- Are the 89-90 MAP cars Speed Density? Or are they Mass Air? Because I have a have a source who says all Speed Density controlled vehicles made by ford stopped in 1988. A MAP read car with Mass Air does not seem out of the question. It wouldn't really work all that accurately, but could work. Now does anyone know for sure?
