I have a problem that has been increasingly troublesome. When driving down the road at times you can press the gas pedal as much as you want and it will not accelerate. It will kind of jerk you like its accelerating then nothing then accelerating then nothing. At first it would only do this when I would run the air conditioner for awhile so I stopped running the air. Then it started happening on long trips and now its happening anything more than a few miles.
