Volks,

My 85 still doesn't want to hold an idle very well.  Start up and run and it
idles usually at 800, sometimes falls to 2-3 hundred rpm when coming to a
stop.  With the A/C on this almost always means it stalls, without A/C runs
about half the time.  Runs very badly at 2-300 rpm, smells of unburned fuel.

Tried jumping the idle control unit, no change
Put in new plugs, cap and rotor, air filter [needed a tune anyway] no change
Sprayed carb cleaner around the engine looks for an air leak, no change
Put in the digitool brain ran a bit rough but no change in the bad idle
situation.

So my questions are:

How does one hook up the diagnostic part of the digitool?  There's an orange
wire out of the brain end of the wiring harness and a red one out of the
display end, where do they go?

What are the normal readings for Temp 1,Temp 2, Oxygen, AFM, Battery, Probe?

 Darrell's site doesn't give this information as far as I can see.

Any ideas of what to look for now?
