I missed your first post, but I gather you have an erratic idling problem
which can't be found for love or money. Join the club. I have a 88' 90Q
with 138K on it that Audi has chased for 6 years trying to find a low idle
speed with AC on when very hot. (Like summer in Phoenix.)
Anyways, if the 100Q is like mine, check for a dwell signal across the two
terminals at the stabilizer. No signal means problems in the wiring
harness or computer. On the 90Q a dwell signal should *always* be on the
stabilizer. (when running of course!) Different techs have replaced the
following items looking for this "missing" signal: Idle stabilizer, O2
sensor, knock sensor, fuel computer, ignition computer, and potentiometer (a
thingy on the fuel injection control unit).
Any questions, let me know. I have a fair understanding of the Bosch KE-3
Jetronic, which I believe you have as well.
