Ok, I am getting a C&L 73mm cal for 24# because i am doin a H/C/I swap with 24# injectors.. My searching has dealt me no straight answer.. My car had idle issues and rich running before i started the swap. i had tuned every aspect from the IAC to to the timing.. You name it and I checked it or replaced it.. BUT Not once did I fool with the MAF as i figured it was stock.. Well when i dismantled the car i got to writing down part #'s for reference and the only one that didnt match up was the MAF sensor being a F1ZF, i think is for a fox? i beleive my 1995 5.0 came with F2ZF right? I hear people switch over to the fox MAF sensor and the Fox guys use the SN housings. But are the sensors compatible or is my issue with the fox F1ZF sensor?? Do i need to get the right sensor for my year to put on my new C&L MAF??
