Also is it possible to pull and clean the solenoids in order to get proper operation back?

Other issue is going on uphill climbs I can also experience other power loss but no definitive rpm...
Have driven the vehicle 3 times after redoing ground connections, low power p0576 error code is the only code currently showing.
Plan is to chase it to the fuse box and PCM plug and check both.

P0576 is cruise control... weird, but don't think it would affect your driving.
The log looks about the same, pretty rich most of the time at full throttle. Your MAF rate is the same ~163 g/ sec between 7k and 8k at full throttle, which is weird, it should increase with RPM. If I compare to one of my logs, across that range it should be 180-200 g/sec. Sure, some difference in data is expected due to calibration, but overall, something is choking your engine, or the MAF is misreading.
Since it happens in a specific range (although in this log it seems to happen higher than 5200 as well), I would first make sure the intake valves operate correctly, at least the ones you can reach, and then check if the catalytic converter is in good shape, not disintegrated inside.
Your idle seems too high too, it's idling at 1000 after warming up, with a MAF rate more consistent with 800 rpm. So there might be unmetered air in there, or again poor MAF reading. Was this car always a 6MT or did someone mess with a base model auto? Any modifications at all?

I will investigate leaks after MAF to double check. It has always been a 6MT. No modifications besides someone replaced coils and wires at some point with oreilly auto parts special.
