Need Help Diagnosing Cylinder Misfire

Welp! Glad it’s actually misfiring versus a misfire code. Might be funny to say, but my CEL was caused by the thrust bearing falling into the oil pan.

 

Oof! That looks costly

 

What symptoms did that show, and what codes?

 

Cyl 1 misfire without misfire. Knocked a hair in reverse. PO found about a 1/4” of crank play. Sold me the truck and I put a new motor in it.

 

Update: Took my truck to the mechanic and it turned out that my timing had jumped about 3 teeth and my camshafts were advanced. That has seemed to fix the issue at hand and the truck runs well. My fuel trims are still a little off and MAF is slightly high at idle.

I am going to make a separate post but I am now dealing with a P0172 - Rich bank one and after re-fueling it is very bad and my truck doesn't want to accelerate or drive. Almost stranded me on the side of the road but luckily after a bit I was able to get it going and drive it. While driving it will randomly rich out a bit and get sluggish for a second.

Some stats from when the code was thrown going about 60 at 2000-24000 rpm:
STFT B1: -10.9 & 0.8
LTFT B1 -30.5 & -30.5
