What is an "idle up" valve?
Looking over a CIS-E system (O2 box, no knock sensor box that the
GTI/GLI/16V has) there is nothing attached to a AC module to control the
idle like there is in the Digifant and Motronic systems. You are also
right, a idle stabilizer valve is a function of CIS-E. There is the idle
stabilizer which is controlled by the O2 computer and the idle stabilizer
relay that gets a pulsed signal from the tachometer signal. If you turn the
AC on or any other load it will simply allow more air to by-pass the valve
and the idle will remain the same. I have omitted the idle stabilizer valve
for customers who can't afford the big price tag for a new one. I replaced
it with the warm up valve from the CIS system and adjusted the idle for a
nice 900RPM.
From the sounds of things I really don't think you have a CIS-E system. I
think you have a CIS-Lambda system. There are a few quick ways to tell by
looking at your fuel distributor. What color is it black or shiny silver -
if it is silver it is CIS-E, also is there one or two electrical connections
to it? If there is two it is CIS-E.
If there is an idle stabilizer - don't worry about it. If it is doing it's
job the idle will remain the same when the AC is on.
If you have a CIS-Lambda system. I have some diagrams here that will help
you set it up.

Subject: [Syncro] Wiring for CIS-E F.I. in Vanagon
OK, here's one for the record books. I'm getting down to the wire (no pun
intended)
on the installation of my 1.8L inline VW engine, in to my SS Syncro. I
have one item left to
figure out where it gets wired in. The Idle up solenoid valves. There were
two in the VW
Fox system, one been used obviously for the AC . The problem is I need to
establish what controlled the
second valve. Now this is interesting. I can't seem to find a wiring
diagram that shows the CIS-E system running this valve. The Wiring diagrams
I have showing the CIS-E Systems all have a idle stabilizer valve.
This valve (the idle up solenoid valve) came with the Fox motor. It is the
same solenoid valve
that is used on the CIS system with a O2 sensor. A simple valve. I have
the wiring diagrams for several Golf , Jetta, Fox CIS-E fuel injection
systems. They all show a idle stabilizer. Anyone have any
info. on its wiring? I must be missing something here? Any info. would be
appreciated
