Question Asked: the car bucks when engine is cool and/or air is humid
August 21, 2009, 09:03 AM
I have had this car at the dealer 3 times with this complaint, and when the car bucks, you can see the rpm drop even though pressure is constant on fuel pedal. I have told them it's something with the throttle position sensor, but they disagree. No engine fault comes up so they won't do anything even though they have experienced the bucking as well. What now?
