07 ls460 codes p0172, p0175, p0051

I had these codes show up while i was idle. Replaced bank 1 and 2 a/f sensors a few months ago and recently got the starter replaced. Also only averaging ~12mpg according to the display. Any input on how to possibly fix would be appreciated, thanks.

A high end diagnostic tablet or Techstream software will help pinpoint the specific issues.

Did you use OEM sensors? Did you do anything about the oxygen sensor error?

I used Denso sensors. I havent done anything for the p0051. I got the 172/175 a few weeks ago then it left after a few days and i just got them again along with p0051 today
