Glad you solved it, sorry you paid $229.  Ouch.

Does anybody know if the ISV from digifant Golf/Jettas are compatible?
I have a bucket with about 10 ISV's from these cars.

They can't all be bad...

Subject: Strange Idle behavior: Cause found

A few days ago, I posted that my Digifant injected inline VW four banger was
misbehaving.  Newer Vanagons share the same injection system, so this may
come in handy if you encounter an Oscillating or 'hunting' idle.  Mine did
that for a bit, going from normal idle up to around 2000 rpm and back down
in a regular cycle (about 4 seconds to complete the cycle).  Then, the idle
became steady at the high rate..around 2000 rpms..
  After some testing, I replaced the idle control valve.  A pricey item,
cylindrical and silver with two hose connections and an electrical input
connector.  I found one for $229 online and now all is well again.  I tried
cleaning it first, using brake cleaner, but no worky..  For a temporary fix,
should this happen while away from home, you can simply clamp off the small
inlet hose, between the intake and the idle control valve,  with a pair of
vicegrips.  This might make the engine idle a little touchy when cold, but
it will keep the idle revs low enough to drive the van and it doesn't seem
to affect any other performance.
