No idle help...

'88 5ktq. Car stalls when you let off the gas pedal. Runs fine when one is
driving and when holding the rpms up.
I have checked the decel valve, and it appears not to be a problem. I
disconnected the large hose, and plugged the hose and the valve. Same stall
I checked the ISV per SJM web site. My normal reading is 595 mA with the
engine off, which is high according to the site. When I disconnect the
green wire on the coil, 425 mA through the ISV, which is almost spot on to
the suggested 430 mA.
I also notice a distinct click in the vicinity of the decel valve when I
remove/connect the green wire on the coil -- I take it this is good as the
1200 rpm override seems to be doing something.
My next guess is a vacuum leak somewhere. Naturally everything seemed tight
before the hall sensor went south last week. I now have a new distributor
and hall sensor, but it will not idle. Any suggestions? It got dark so I
had to stop looking, so I thought I'd ask before I went to do battle on
Wednesday. I've got a class tomorrow, so no Audi for a few more days :-(
