maf set up question

The autothority maf is set up on a '86 3.2. The engine surges about 400 rpm at idle. The air/fuel ratio looks fine. Any ideas. Or can someone point me to the installation instructions. I bought this used from a friend.

Call Autothority (703 323 0919) or email them for the instructions. The potentiameter in mine began failing a few years ago. I had to have the system reset when I replaced it. Not a big deal but I didn't have the meter nor time nor experience to adjust it. BTW I have 75k miles on it and am very happy with it. Car runs cleaner if nothing else.
