Well quick update. Car runs perfect with this reman maf. I really should go back and check what year the car was.

Anyways the PO said he had the whole TB replaced for some reason that I forgot to ask and said he had the old one laying around and brought it over. I grabbed the original maf and looked ok but instantly after putting it in it started doing the same thing it did with the older maf. It started surging and causing lights to dim.

Whats going on here? From what I see the reman 97-98 looking maf works since there is nothing in the way of the sensors and its basically a open spot. Unplugging the maf makes the car idle higher.

Should I just leave it be?
