I’m now getting banks one and two too lean. P0171 and P0174. Getting ready to change out PCV. Hoping that’s it.
I have a voltage reading on bank one maf sensor of -30v which seems odd. The maf sensor is not throwing any codes. Bank two is reading at 1.5v. Anyone that can verify those readings?
only getting system too lean which seems to be a vacuum leak and no other system malfunction.
checked oil cap and cleaned debris. No apparent vacuum leaks anywhere but have not smoke tested yet.
open to all theories.
