Hi,
Thanks for the update. Something isn't making sense. Are you certain there are no vacuum leaks? If you are unable to perform the relearn with the directions I sent, you may need to get a scan tool that can communicate with it and reset it that way.
I attached what I have for the throttle relearn below. It includes what I sent before and how it's done with a scan tool.
Take a look. Maybe something will jump out to you.
Let me know.
Joe
