yeah get it checked out, but first, did you always have this problem? and what did you do different prior to the problem? how is your MAF sensor?

sounds like the accelerator pedal sensor or the tps sensor. Beware the accelerator sensor is on national back order.

Cheapest thing to try first would be good gas...Bad tank of gas can mess with all sorts for stuff. Mobil, EXXON, Shell, Cheveron make good 93+ oct. fuel. Bad gas can give you hesitation and loss of power during acceleration.

If this doesn't work (give it a full tank of good gas by half a tank no more problems should accure). If they do still accure then conrtrim1 might be on to something... go cheap first though
