I just ordered a maf sensor and installed it on my mustang. I used to have the factory maf sensor and switched it to a bbk 76mm maf. I have a 1991 mustang gt with 24lb injectors. The problem that I'm having is rough idle. I let the computer re-adjust by disconnecting the battery, but I am still expiriencing the rough idle. My car ran perfectly fine before upgrading to the new maf. I already bought new fuel pressure regulator and adjusted it from 40- 50 psi, with no luck.
