The air flow meter should move much further than that, even at idle. It
should never able to close with the engine running.

You have a major vacuum leak, bad intake valve or piston or swapped ignition
wires or the spring was tampered way too much.

Not having another vanagon around to compare to I ask the experts.  I have
read many contraditory and misleading posts on the internet on "Vanagon
syndrome".  I don't know what is true.

1983 waterboxer

So out to the vehicle I went cleaning grounds, checking wiring, resistances,
components, etc.

about 1/2 throttle position it bogs down, driving or sitting with a spare
temp sensor two installed, o2 sensor disconnected, idle regulator bypassed,
etc, none of this impacts it. But If I hold the AFM wiper arm so it does not
go to the point that drives it to bog, it speeds up great and runs like a
champ.  The wiper also seams to loose its resistance reading about there
too.

So is the AFM trash?

Is the afm arm supposed to flutter like this during normal steady state
operation ? Because it does

Does a new AFM fix the fluttering, or is there something else I need to look
for to fix the flutter?


Other item of note to those who read this far, if you need a flat 4 subaru
engine out of a outback there was one at the yard I went to yesterday, in
the Memphis, TN  $250, sorry I don't crate ship.

Thanks for any advice, and if I am bothering you please remove me from the
list.
