Hi,
Is the idle speed consistent, and correct? Also, are you getting any other codes?
This could be a few things. I attached the diagnostics below for P0505. It will require a scan tool. Take a look through them and let me know if you feel comfortable doing it.
Also, if you haven't cleaned the throttle body, you may want to try that as well. Here is a link that explains how it's done:

Let me know.
