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.
