another strange behaviour - '86 930

Understood. I agree it doesn't seem to make sense. Mine was going well with ox disconnected running slightly rich but timing seems to affect afr and drivability depending on how rich you run.
I would first set timing as per spec, (I think it calls for vacuum lines to dizzy disconnected and plugged) check the system pressures and if all ok, set idle mixture with ox disconnected by reading voltage on ox. (As you don't have AFR) Then plug everything back in and see how it goes.
