I'm trying to debug a rich condition in my 91 Spider. One of the only remaining things left is that the AFM may be bad. It has the right resistances across it with no flow, but who knows what it is doing at mid-throttle.
Would anyone in the Boston area be willing to lend me one from a series 4 Spider for a day, so that I can see if it is the cause of the richness, which is making me poor.
The specific AFM is numbered 0280202020.
