Running rough when warm???

I'm new to the forum and MBs in general, but my 94 C280 has started running rough when it heats up. Until then it runs like I would expect a MB to run, but as soon as I've driven more than 15 miles or so in the city, it's rough. I can put it in park and it still idles rough. It does not get any worse once it starts doing it, but it is very annoying and probably detrimental to the health of my motor. Any help would be greatly appreciated!<br>
Thanks, Adam.
