Figured out the lean idle could be a vac leak. Does this sound right?

Found out what the vac leak was. My threaded plug I used for the EGR port on my intake had fallen out. Now my idle afr is right where it should be.

Thanks for the lack of help

Is $165 about right?
I am having MAF problems and would really like to see on a more detailed level what is going on.
Thanks in advance.

14.7 is ideal for emissions, 15-16 for fuel economy but I doubt we would see that I don't think we have semi closed loop operation..12 for powaaaa!
