My '95 300D has started to miss when starting from cold. When warm, it starts smoothly. It blows considerable smoke when cold and running rough. This roughness lasts only 20 seconds and is accompanied with a louder than usual sound. Other than that the car runs great. It has 190,000 kms. on it. Any help with this problem would be greatly appreciated.

Sounds like an injector, glow plug, pump element check valve, compression type of thing.

Steve covered most of the basics here. What I think he is saying is, go and at least have some diagnostic time spent to narrow down your options, then come ask a more precise question.
Thanks
