hard start
If your car starts o.k. when cold, look for a temperature related problem. I suggest you check out the engine temperature sensor that inputs to your fuel injection computer. I believe your car has three temperature sensors; one for your temp gauge, one for your aux fan and the one I suggest above. On my 560SL, that sensor is located at the front top of the engine easily accessible by removing the air claner housing. It is the sensor with two wires. Yours may be the same.
The sensor is relatively inexpensive (I think I recall about $40.00).
