Larry,
Sounds like a problem with the idle control valve. Pinch off the hose
between it and the intake elbow. If the RPMs drop the valve is indeed the
source of the extra air. If so, remove it and flush with carb cleaner.
Good Luck,

I agree it would be nice to have it operational (which it has been for 200K)
  What are your thoughts on why two different units give same symptoms (over
2K RPM at idle)?  Haven't noticed any difference with dash lights with the
unit disconnected.

Nice thing about the idle stabilizer; it produces that surge of rpms when
you first start the engine. This kick starts the alternator to turn off
those annoying red lights on the dash.
