About 2 weeks ago I was driving on a wet muddy road and ever since that time I have been having a problem with my car idling rough while sitting at a stop light. The car runs fine while driving. No problems with the transmission.

The most common cause of a rough idle is a vacuum leak. Have you checked for that? Also, make sure mud didn't get on the crank sensor.

Let me know what you find.
