My other sisters old golf did that exact thing. The bearings in the air fuel mixture flapper were sticky and there was some goop on top that was also making it sticky. Dad cleaned it all up and the problem was gone. He always told me if it bounced more than once or did not bounce at all when you picked it up and dropped it, then the car would not idle properly.
I am not sure this would help an old pro like you, but just thought I would say it anyway. Maybe someone did already, but used short form and I missed it.

This just arrived though.
BIG thanks to Richard (cyclops594) for going out of his way when at the yard to pull the harness, send me photos of ALL the connectors while he was there, boxing it up and getting it here in 2 days from California! All for a GREAT price.

I'll eventually check the comtinuity and resistance of all the wires and find out what was actually causing that. My guess is either the CTS, O2 sensor or the potentiometer on the fuel distributor. It wasnt the DPR since the idle went to like 2500 when i disconnected it and i was able to get a reading with the test harness. It would be nearly impossible for a knock sensor wire to go bad since those are so damn thick. These things are technically complexly simple. Not very much that controls the engine. I'm still going to replace the fuel distributor when it gets here and then do a final tune on it. Then we might start on the body and the rest of the interior. Headliner was jus done.
