it's been foggy as all get out here in Missouri......I get in my car and hit the traction control button (out of habit) and drive off. I pulld onto a side street and got a little wheel hop, no biggie right? From then on right at 2200rpms I kept hearing some sort of odd buzzing sound coming from the right rear of the car......dreading I screwed something up I stopped and looked everywhere all to no avail. Tonight I stopped for gas after work and noticed a bag of kids toys on the floorboard that use to be on the seat..........I guess they were vibrating together because I picked it up and no more noise...............
