Well I'm happy to report that my compression test on all 6 cylinders proved to be good! Especially cylinder #4 where my misfire code was 馃榿. Nothing below 120 psi after 3 strokes.

I have not detected any vacuum leak using butane around vacuum hoses. Disconnected the brake booster vac hose and plugged it. No change in the map reading so I do not suspect the brake booster. No trouble with brakes either. Replaced intake manifold gasket and throttle body gasket, the air intake hose is leak free, no change in the MAP reading. I can not hear a vacuum leak. Replace MAP sensor?

Have a manual vac gauge? What does your scanner show for map voltage at hot idle, maybe your scanner isn't reporting psi correctly.

No.
Going to see what my MAP reading is on my other Crosstour. May swap sensors to see if the reading changes.

Fuel pump would effect trims on both banks. Things that are the usual causes of 1 bank trims being off
A. Cam timing off
B. Vac leak
C egr ports plugged and egr not closing all the way
D. A/f sensor biased
E. Cat being plugged/restricted
F. Valve on the bank out of adjustment
G injector(s)
H. Have seen cracked air intake tube on a maf veh effect only 1 bank.
Map v would be helpful information

Ty for the list.
I am suspicious that the EGR may be the problem.
I checked the MAP reading on my other Crosstour. The reading is the same and has very negative fuel trims, but both banks. 馃う鈥嶁檪锔

Welp, after going over this engine, and unable to find a vacuum leak to attribute to negative fuel trims. I'm pleased to say that after buying a professional scan tool, I was able to reset the throttle, and my fuel trims are back closer to zero. It smoothed out instantly! It's not dead yet! 馃榿
After the compression test checking out great and its smooth again at 268k... This is definitely a banana dance moment!

New radiator and AC condenser going in this week, hopefully back on the road next week.

Little bangin here, a little there. Large vice grips to bend metal straight again. Got it to where the radiator and condenser can sit in their cradle again. Little touch up primer, looks new again. At least until the next hog strike. 馃う鈥嶁檪锔

The computer dating service matched up a lonely DIY auto mechanic from TX with a comprehensive diagnosis companion.
The relationship will be platonic and wireless.
馃 Hmm. Don't think this analogy will work for me.
