TL;DR bad spark plug
After some troubleshooting I found the culprit. I started with re-seating all the coil packs to be sure I didn't mess anything up there. I unplugged each coil pack one at a time. Miss-fire got worse on every single one. I went to Advance Auto Parts to pick up a spark plug cap coin thing. Found one at 0.48 while the rest were at 0.50. Very very softly pushed to gap each to 0.51-0.52 as OE recommends 0.50-0.53. That didn't fix the issue...
I then took a break and ate.
Came back out and started pulling each spark plug and replacing it with the same old one. So, took new one out and put old one in. Started car for a minute to check for misfiring. Then took old plug out and put new one back in if it didn't stop misfiring. Of course, got to cylinder #4 and it was the bad one. Would have really loved the a CEL to kick in so I could've scanned it and found the cylinder faster but of course not. Old spark plug is in for now. I'm past the Amazon return window online so I'm going to try to see if I can call tomorrow and check if I can return it anyways...
I will be adding pictures once I get my final height and wheels on, exhaust impressions, and suspension impressions once I drive the car a bit. I just want to drive it a bit and enjoy the car because of how long it has been down.
