I'm getting a lean code on both banks. I'm wondering if its just the o2 sensors or if there's some other problem I'm not thinking of. Any ideas would be greatly appreciated

 

for a start check the fuel pressure, fuel filter, any other codes?

 

O2 sensor low voltage on driver side bank second sensor

 

I changed the fuel filter thinking that could be it but no change

 

Wat should my fuel pressure be at? Yea yea dumb question but there r a few diff ideas for proper pressure

 

have a look here.
