The st fuel trim is 99.2% for bank 1 sens 2 wayyyy different then for any other bank what does this mean

Ignore the 99% fuel trim for all downstream sensors. They don't contribute to fuel trims so that 99% value means not applicable. Many scanners will display N/A for those PID values.

The operating temp code could be concerning.
Is the engine getting up to operating temp, meaning about 200°F or so? (look at the ECT PID)
What temp thermostat are you running?
Has the radiator been replaced? If so, with what brand?

I just cleaned my MAF and it cleared all codes on its own. I had B1S1 P1133
and no activity on B1S2. All of a sudden they're reading and codes are gone

The exh manifold seems good except the two front bolts are snapped as usually so…
Bro they sell a clamp to fix the broken manifold bolt issue. I used one on the front driver's side bolt and last firewall bolt. Firewall bolt was PITA but the front one went on on 10 mins.
