Either you have a vacuum leak, a bad throttle body position sensor, or a bad throttle body.
If the throttle body is drive by wire (electronic) then it would be a bad throttle body.
If the throttle body is drive by cable (manually driven by a cable connected to the gas peddle) then it would be a bad throttle position sensor.
If the throttle body is bad the check engine light wil lbe on. If it is on have your codes read at your local parts dealer for free, and this will give you a clue as to which pices/parts you need to replace.
Have the car leak tested and the vacuum linse inspected for leaks as well.
