Please can anyone fill me in on how to adjust the fuel mixture on a 1990 2.0 (fuel injection) Audi 80?
It's running rich - heavy fuel smell, rough idling when warmed up, exhaust smoke etc.
Thanks in advance.

I assume this is Bosch KE-3 Jetronic?
You can't adjust the running mixture, as such (the idle mixture is adjustable via a threaded stop on the air metering unit).
You really need to get this looked at professionally, I would say.
