David- I did'nt see that you checked the idle stabilizer relay, a common
culprit?

I'm trying to get his 2.1L motor of mine to idle correctly before I remove
it from my Single Cab and install it into my Westfalia.  There is no
tachometer in the Single Cab, but I estimate idle was around 2500 rpm before
I started messing with it.

I corrected the closed throttle switch not engaging, set the timing to stock
values, checked the TEMP II sender (OK).  The throttle valve butterfly
itself seems a little worn, I can move it up and down a little and when it
is up, the idle drops down to near normal values.  Pushing it down (1mm)
will bring it up to a 1.5 to 2K roar.  I have swapped the idle stabilizer
valve out with a known to work unit, the idle bypass valve is working and
pinching the line makes no difference.

To me, it seems like too much air is getting past the throttle valve and I
may need a new one.  Will a 1.9L throttle valve work?  Anything else I
should try?
