There was a vacuum leak. Break booster hose was split, have replaced it. System too lean codes have cleared but below two codes(P1073 and P1057) have persisted
Please advise how to solve this.

I had a dealer diagnose this issue. My air oil separator diaphragm had gone bad(which is located inside engine). No more squeaky noise after replacing it.

I am getting a squeaky noise from under the hood. Was not able to identify the exact location of the noise. I have changed my serpentine belt, assuming loose/worn out belt would have caused it, but the noise didn't go away.
Sometimes, I have seen intermittent "Oil Pressure too Low" warnings on the instrument cluster, but the warning goes away when I turn off the engine and again turn back on. My oil levels have been pretty stable. I have recently changed my engine oil too, but the noise is still persistent.
I am also thinking to replace idle pulley, not sure if this would fix the issue.
Can any one help me diagnose this.
P1287, P0393, P0391, P1073 faults System too lean at idle bank 1/2

Tried clearing the codes 4 times, but P1057 and P1073 keep coming back after driving some miles. Any insight on how to check this issue would be helpful.
