I'm attempting to do a TB cleaning, however my MAF sensor screws are torx, T-20 I believe, and have a post in the middle of the head. None of my Torx bits have a hole to accommodate it. Is there a special bit? If so where can it be found?

you can use a special security bit, available at most hardware stores...

or you can just use a dremel or hacksaw of some type to notch out a groove so you can use a flathead screwdriver

I have some screws that I could send you to replace those stupid ones once you get them out, if you want them, PM me

Thanks for the tip, the hacksaw worked.

I imagine this contributed to my stuttering:

Maybe..

You should notice a difference once that is all cleaned up.
