Chasing Lean Code bank 2 and MAF codes

Hello,

I have been troubleshooting P0174 (lean bank 2), P0100 (MAF A circuit) and P0113 (air intake circuit A high).

I have cleaned and ultimately replaced the MAF sensor with OEM. No change. I have checked the pins in the connector, they are in good condition.

I have smoke tested the intake twice. I cannot find any leaks. The inlet ducts have been removed and inspected and no cracks tears etc. When performing the smoke test and I remove the oil fill cap, I do have smoke coming from the oil fill port. I’m not sure if this is normal or not.

Any other ideas or things I need to check?
