Mine did that at first then the accelerator pedal position sensor went out. If you throw the p2121 code that's the sensor I have a place to get one at a third of the cost just pm me.

Black maybe you just had a fluke and re setting your comp fixed it I could temporarily fix mine by turnin key on slowly pressing the pedal to WOT then slowly releasing the pedal then repeat once more. But eventually it will totaly give out.
