For everyone struggling to get their idle air relearn to take with the "pedal dance" method, there is hope. After cleaning my TB's I started getting the high idle and code P0507.
I tried for about a week to get my idle to relearn. Then I found this

Then the next day while I was sitting at a light waiting for my check engine light to turn on. I noticed...H@LY $Hit, my car is idling at 600 rpm! It finally had worked!
TRUST ME. IT CAN BE DONE!
