I just purchased a 240sx 1995. I keep getting code 12 and it's for maf. I have replaced maf and swapped harness connector . I wanted to know if there is a way to shield wires from the maf from getting electrical interference . The maf harness connector wires 2 of the 3 are shielded and i wanted to know if there is away to cover them to see if my wires are getting noise.
