Have a '95 C280 w/ 82K miles. When stopped at a light and waiting in gear will often get a quick slight shudder like a missfire. There are never a series of them and they are much less noticeable if in neutral. Usually have to wait 30 seconds or more after the first one to have another one happen. Not noticeable if the rpm is any higher than idle speed.

Appreciate any comments re possible cause and sollution. Thanks
