Bank1 unstable fuel trim

UPDATE!

I finally found the issue that was causing my problems.

I had the plugs for the ignition coils for cylinder 3 and 5 mixed up.

I couldn’t find a wiring diagram for VHR harness so I use a DE as reference.
Sure enough, it matched.

When I was plugging everything up, I thought the lengths were obvious enough to determine which cylinder they went to.
