Answers :

A few things could. I'd take it to Autozone or some place that will scan your car with an OBDII scanner for free. Would like to know what codes are popping up to give us a clue. 1 thing I've seen is chaffed wires in the main wiring harness causing problems. Another popular one is a bad gas pedal positioning sensor or pedal assembly. Also a transmission controle module. See what codes pop up and we can go from there.
