If the check engine light is on, I would have the codes read. Sounds like you have a fuel/air mixture issue. Before spending money of parts, I would start by buying some throttle body cleaner and cleaning the throttle body and Idle Air Control valve. Then buy some MAF cleaner by CRC and clean your Mass Air Flow sensor. See if that makes a difference. If no check engine light, post back with results.
