Intermittent throttle problem

[pp270]

I have a 2000 Alero GLS V6 with 215K miles. The car has been experiencing intermittent throttle issues where it will hesitate slightly. Immediatly after this hesitation the trac control trio of lights come on. I don't think this is the bearing as there is no wheel noise to accompany this. Also the trac control lights don't remain on when you start the car the next time. If this hesitation occurrs when using the cruise the cruise control will be disengaged.

I also scanned the car and pulled a P0341 and P0440 code. (cam sensor and evap). These codes have existed for the last two yrs long before the throttle hesitation issue has cropped up so I don't think it is related.

Any ideas of what this could be?
