I thought I had seen about every kind of weirdness which a Vanagon can
exhibit, but I am open to any and all suggestions regarding this most recent
bout of perverse running.  At times, my '90 Syncro idles at about 2K.  The
strange thing is that when it is idling high, if I hold it with the brake and
release the clutch slightly, I can drag the engine speed down to 1K and it
will hold that speed rock solid until the throttle is blipped.  As the engine
has been gone over quite a bit, this one has me stumped.  Hopefully someone
will have had the same symptoms and he can save me untold hours of chasing my
own tail.

Thanks, one and all.
