my buddy's GS-T did the same thing, we came to figure out it was the speed control, that is a part of the electrical system.

-Worst case:ECU/ECM needs complete replacing
-Best case: I am wrong, OR the speed control needs replacing,
(i.e. about 25 out of your pocket)

peace

OR......

It also could be the throttle bodies are really dirty or are being partially blocked by something. I helped fix an Olds for a friend, removed the throttle body and found about a 2 inch carbon deposit build- up. Nasty-*** job. After clean-up, the car returned to normal. Idle and acceleration were renewed. Or it could be something else. lol Good luck, O and if it is the throttle bodies this should help....peace.
