I'm having a problem with major high idling (and surging) as well. Replaced
the Idle Stabilizer valve (on top of engine), opened up and checked the Idle
Stabilizer Control unit (behind taillight), and  checked every single !$%*&
vacuum line on the van.

If I disconnect the valve (on top of engine), the van dies. If I pinch the
tube going into the AFM, idle returns to normal.

What could it be?
