Lean Miss

On my 1992 500SL, I recently had the 60K
mile maintenance performed. I also had
the fuel injectors replaced to fix a
cold start/warm start idle "rumble" problem.
The engine would rumble for about 2 sec then
smooth out.

The idle "rumble" is fixed. The car starts fine
and idles very smoothly except for an occasional
lean miss when in drive and at a stop light.
The idle is at 600rpm and very smooth except for the occasional lean miss. In park, the lean miss is more frequent.

Interestingly, when the O2 sensor is disconnected,
and with the car in neutral, 700 rpm, the lean miss is gone. I had the O2 sensor replaced but the lean miss problem is still the same.

Any ideas?
