I placed the shift lever in reverse and depressed the accelerator pedal. The car accelerated rapidly. I depressed the brake pedal very hard and held it down. The car alternately stopped, accelerated, stopped, accelerated etc 3 or 4 times before coming to a full stop: total distance traveled - approximately 30 feet. I repeated the above procedure in forward gear and got the same result. Prior to this incident the throttle system did not appear sticky or off-normal. Post incident, the throttle appeared slightly sticky. Approximately 18 months ago I reported a sticky throttle to my Buick dealer, they serviced the throttle system and the problem was solved. As stated above, the throttle did not give indication of a problem this time.
