Hello. I was wondering if I could get some help with these codes?

-P0455 Evap Emission System Leak(Most likely Vacuum Pump with Solenoid replacement and Vacuum elbows/valves on intake manifold) Code previoulsly cleared, came back on.

-P0153 O2 Circuit Slow Response (Bank 2, Sensor 1) most likely O2 sensor. Code previoulsy cleared, came back on. Should I replace the Bank 1 as well?

2 above codes have come on before and have been cleared so I will start there. But recently after battery replacement, these new codes came on which I cleared.

-P0172 System Too Rich (Bank 1) Possibly MAF Sensor. Can't seem to find part number for this. Dealership gave me MAP sensor #

-P0172 System Too Rich (Bank 2) Possibly MAF Sensor.

-P0175 System Too Rich (Bank 2) Possibly Fuel Injectors need cleaning (Although I do not have any symptoms of FI needing to be cleaned.)

If anyone could give me some advice, it would be greatly appreciated. Thanks.
