My 2005 might be different but I had rough idle problems and after cleaning the throttle body I also cleaned the Mass Airflow Filter (MAF). I then found a vacuum line connection that runs from the rubber plenum to the back of the intake manifold that was completely disconnected at the manifold. The car now idles perfectly.

You may also want to check to make sure there was no additional debris along the edge of the throttle body that you may have missed, such as at the butterfly and the rod junction. What did you use to clean it? A toothbrush works well.
