Re: Lean Bank1 and Bank 2
What year engine, and is the fuel system a return or return-less?
If both banks are lean, it can be the FPR on the return system. This will be at 58-60 psi all day long no matter what throttle position.
If it's a return-less system, then it's the intake gaskets. The orange style gaskets are known for leaking. The newer ones are green, and you can get the A/C Delco or Felpro brands. It's an easy job.
really clean looking intake pluming !
