DTC P0172 - System too rich on bank 1.
DTC P0174 - System too rich on bank 2.

1) Replaced air filter + cleaned MAF sensor.
2) Reset cleared codes.

Are you asking for additional things to try, or stating that cleaning the MAF and replacing the air filter fixed these codes?

The problem seems to be resolved, but waiting for the drive cycle to compete.

Did you review the sticky for these two codes?

Yep, I mis-read the code number. I focused on the P0174, which for what it's worth is a Lean code, not Rich. Did you really have a P0175?
