Dear List,
 
I'm trying to tell if I need a new air = flow meter for my '86 Vanagon.
 
Can anybody enlighten me on how = resistance should change
as the vane moves?  My manuals = (even Probst) are vague.
I have two AFM's in hand.  Both = show similar resistance changes
with movement, but one seems to have = some drop-outs.
 
Couldn't locate anything in the archives.
 
thanks,
 
Steve
