Just an FYI in case it may help someone as they search.
‘99 LC 465 k miles. I have been having all three of these codes come up. Two codes showing system running too lean on each bank and P0125 coolant temp code as a result of the first two codes… so says my research.
I changed sensors, new coolant temp sensor and cleaned MAF. Codes still present.
Then I changed the fuel filter. Codes haven’t come back yet. The brown fuel coming from filter might just have been an issue and proof of a good working filter.
Hope this continues to be the solution for mine and any others.
