What does it mean when...
What does it mean when the car bucks when I accelerate quickly? I have a 2003 S Type. Example: If I am deccelerating to stop at a light but the light changes to green before I can stop and so I have to accelerate again. The car will jerk/buck with hesitation before accelerating. The "bucking" is also more frequent when the AC is on. What does this mean? My mechanic recommended that I take the car to the dealership to have it "reflashed."

There is a re flash that would apply to your vehicle. It is for a slam shift though, which might be what your describing. I do think it would make since to try that first, before diving in too deep.
