I had the same problem with both of my 300SELs. My current one is an 89 300SEL. I had a cold idle problem that turned out to be my Air Flow Meter. Whem my tech replaced it, it also fixed my surging idle. What appears to happen is the meter gets a burn mark on it at the idle position, and it searchs for the right idle. You can have it checked to make sure. It is expensive to replace so its not a part you want to just try out.
