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.
