I hope some one can help with this problem I've got. The car is a 2000 S80 T6. About a month ago I was driving on an interstate highway at 70 mph when the front right tire started to vibrate. It seemed like a flat tire but wasn't. Since then, the vibration can return after the car warms up, thirty miles, maybe 100. I've had it checked out by a dealer and they could not trace the problem other than guessing it to be a throttle body problem. The car stalled out on me three times today and the problem when just starting can be reduced by throttle modulation. Any one else have any similar problems or would like to take a stab at this? Thanks
