    I would check the Idle Air Flow Motor, it ajusts your idle electronically, and they get carboned up, often gets chunks of carbon between the motor and its seat, and cannot ajust idle, they generally bolt to your throttle body, also loose throttle body housing.

    Im having the same problem with my buick. The scanner is teling me its a quad driver module circuit failure but what im finding out is since its a " quad driver" it runs four things, mostly relays and lights. My best bet would be a fuel pump relay or something like that. best of luck.
