2000 Buick Century Owner Comments

problem #4

Nov 302004

Century 6-cyl

  • Automatic transmission
  • 75,508 miles


The consumer experienced unwanted acceleration on 2000 Buick Century. Sporadically, there were super high revs when the vehicle was first started. Then the consumer had to stop the car and restart it again in order for the revving to go to a correct idle speed. The car has been to the dealership 4 times over this problem. This did not happen for the first four and half years. The dealer has replaced the throttle position sensor two times and the computer once. The consumer is still having the unwanted acceleration problem. The dealer can't figure out what the problem is.
