Alan, do you have the Bosch Technical Instruction manual? (yellow cover)

Dunno if it helps, but from p20:

The control pressure acts through a
damping restriction on the control
plunger and thereby develops the force
which opposes the force of the air in the
air-flow sensor. In doing so, the restric-
tion dampens a possible oscillation of the
sensor plate which could result due to
pulsating air-intake flow.

(my emphasis).

So even if you do have lumpy cams, the damping should take care of it. Assuming you've checked/set the WCP to the correct value, it can only be the damping function of the control plunger in the fuel distributor not working as designed, no?
