“On 9-4-2011 I left tallahassee, florida. As I got to the edge of town I noticed it started to idle slightly high. By the time I got to thomasville, georgia, it would accelerate to about 45 MPH without any acceleration pressure and the brakes were required frequently. Between thomasville and moultrie, georgia, it would accelerate independently but it would drop down if I pressed and released the accelerator.
