The AFM develops bad spots, usually right in the range where you use it the
most.  When I put a new AFM on my '85,  I noticed I could smoothly increase
the engine speed from idle to 3000rpm.   With the old one, it would sort of
sit at idle, then jump up to 2000rpm or so.  It was impossible to hold the
engine speed at 1500 rpm.  I believe this is an easy way to check out the
operation of the AFM.  The capacitor fix may work for the Vanagon Syndrome
(see archives), but it is a patch at best for a worn out AFM.  Vanagon
Syndrome is easily verified by shutting off the engine and allowing the ECU
to clear.  If your problem persists, it is not Vanagon Syndrome.

Have a question about my AFM and the trouble it seems to get
while running, anyway I'm going to put that cap inside the AFM
TO CLEAR THE cut out at speeds, 15v 22mf cap mod.

Question when the AFM goes bad does it just go bad all they way?
this is the part that reports to the ECU huh? kinda costly also

Thanks
Joe
