The AFM in my 91 turbo just gave up the ghost:aigo: . I am attempting to track down the correct part. My local parts dealership has two options on his screen. Both of the items are produced by Deckarnly on the east coast. One is listed as an Air Flow Sensor (part#1570177) and one is an Air Flow Meter (part# 1580204). I would like to know if anyone out there has run into this dilema before, and advice on which I need to choose. Also if anyone happens to have a used one available for sale I would like to know about it. Thanks
