Loud (rough) Idle.

2002 325xi with about 113,000 miles. Been running like a champ until about 3 weeks ago when I noticed that whenever I'm idling for over 10 seconds or so it begins to rumble periodically. It's a deep vibration that comes in about 3 - 4 second intervals. Kind of worrisome. Any help would be appreciated. :tsk:
