I'm chasing the same symptoms in an ur-quattro (1988 MB engine, two knock
sensors, MAC12). I've eliminated compression, plugs, plug wires,
cap and rotor, and the coil.
I suspect either the metering head or the wiring harness between the WOT
and the ECU. I've dialed in a bit more mixture, and that improved it
so I'm leaning towards a dirty/clogged metering head.
What mileage do you have? Mine is 134.5k.
