I am working on a 89 560SL with a between complete warm-up hesitation. The car takes a little longer than usaul to start cold, but runs great cold. As soon as it warms up some the hesitation or stall if you jam it fast. when fully warmed up the car runs near perfect, exept for a very slight miss feeling if you accelerate hard. I would appreciate any input on the matter.

A couple of things. Have you checked the fuel system accumulator?? Make sure it is OK...Also be sure to check the overvoltage relay.
