Benz..yes, I do have the 103 SOHC... as do all 88 & 89's (I think).

When stopped at a light, after running at higher speeds, it will just hesitate a bit for a split second. It seems to me to be sporadic. Never stalls. Not noticable under cold startup.
I live with it. Had it a long time, no better no worse. When it starts getting worse, I'll tend to it. I don't want to go on an expensive part fishing expedition.
