Ok bouncing idle means that you have a sensor that is on your Intake manifold that is acting up. It will not show on your code reader because it tells the computer it is acting right. Look around the intake manifold area and you will see it attatched. It is commonly called the throttle positioning sensor. It can be taken out and clean up on the contact surface with very fine sandpaper.
