I have a '99 9-5 with 33k miles that's developed an annoying habit. While idling at a stop or moving very slowly in forward or reverse (while parallel parking, for example), the car throttles up briefly, then drops back down to normal, only to throttle up again before dropping back. The cycle continues until you really step on the gas or shift into park. The phenomenon also occurs when you first start up the car and shift into drive. Adding to the frustration is the fact that the car doesn't do it all the time. When I took the car in for its 30k service, the dealer couldn't duplicate the trouble. The car did the same thing back at 17k miles, and the dealer replaced the throttle body. That seemed to do the trick -- until recently. Any suggested diagnoses and cures? Is it possible that yet another throttle body would go bad so quickly? Thanks!
