I really don't know, but I suspect that's not the problem. Wait a
minute.  '84 5000?  I think you need a turbo fuel distributor.  OTOH, if
you can use that fuel distributor (which I doubt), then you know what
they say, "It's fuel or spark."  Maybe your coil is on it's way out?  Is
it actually leaning out or just appear that way? If the fuel pressure is
indeed high enough, then I would guess the spark is faltering and
therefore giving your "stumbling."  Have you checked resistance on the
idle and throttle switches open and closed and and especially the intake
temperature sender?

I really don't think a fuel distributor from a NA '84 5000 would supply
enough fuel.

  Hi Ingo,

  This is the preliminary report I received today after the mechanic had
fitted a "new" fuel distributor

  "The distributor is a known working unit from a 1984,  5000.  The duty
cycle as the vehicle warms up starts to work at 55% duty cycle and
fluctuates up and down needed.  The problem of stumbling under
excelleration is happening at 3bar regulated pressure. The car runs well
up until that point". 

  Could it be that an '84 5000 regulator is not compatible with a 83

  Thanks for your interest.
