So I think I finally got it. After rewiring nearly every circuit under the hood, I decided to check the resistance of everything. Turns out I had an intermittently failing MAF sensor and a high resistance ground on the ECM (line 12)
After rectifying those issues, its back to nearly tio top performance. After about 45 minutes on the freeway I had a little stumbling when I came to a stop, but I'm chalking that up to me fiddling with the idle screw and the TPS probably needing more detailed adjustment.

Ive come to the conclusion that it'* either A: gremlins, B: still a bad ground SOMEWHERE on the car C: One of the new parts I put in came out of the box bad D: The idler screw is WAY out of adjustment.
Sorry I can't be of more help to you.
If you want, drop me a DM and I can go over what all I've done in detail with you.
