Darren, the official way to test the idle stabilizer is to disconnect the
stabilizer (connect in and out plugs together) and see if the problem goes
away.  Of course, nothing with a Vanagon is free; and doing the above may
create some other problems.

First of all, the tabs that are used to mount the stabilizer are brittle and
tend to break when you disconnect the connector plugs.  Second, if you do
encounter a driving situation where the stabilizer would normally keep the
engine going, you may stall the engine.  Third, given all other factors that
seem to affect idle speed, I am not sure that I have solved any real
problems with a new unit.

If others have a serious disagreement with what I have written, I would like
to discuss.  Also, when was the last batch of these stabilizers
manufactured?
