How do you look at data in this format? I tried, but I can only look at data plots. I have a hard time just looking at the numbers. You might want to try and save the data in a format that can be more easily plotted. Personally, I think it is easier to diagnose problems.

I don't know what scanner you are using, but the way I see it, your IAC is going full open in Park (or at least at 0 MPH). If it is full open, there are a myriad of problems that you could have. The most common is that the throttle plates are closed too far, making all of the bypass air go through the IAC passageways.
Set the minimum air rate.
Then scan again and stop revving it. Let the values stabilize. It is kinda hard to tell what the IAC really wants to do if your RPM is going from 800-3000
and your TPS is going from .7-66% -Matt-
