Just finished putting a new turbo in the 82 245Ti. Car won't idle now. I'm trying to figure out what I did that might have caused this. While I was in there, I cleaned the fuel distributor and control plunger with a buch of carb cleaner. I didn't disassemble it, just sprayed all the junk off from underneath.

I've been fiddling around with the throttle rod, and opening the butterfly in the throttle plate that way to get it to run at about 1500 RPM. If I then manually click the throttle switch to put it in idle mode, it dies. Another interesting thing is the (new) O2 sensor is reading about .05 volts like it should but if I disconnect it from the harness, it dies. I ran the idle up to about 2500 and tried again, it kept running but the revs dropped way off, like 1500 rpm lower.

Basically, I'd like to know where to start. I've got a Bentley but am not really sure if I have a CIS problem, Lamda problem, or fuel distributor/plunger problem.

As always, thanks for any replies!
