P0174 help
I have 2007 v8, hydro locked the motor last year, put in a used replacement and have about 10k on the new motor! Every 900 miles or so it is throwing a p0174 or Lean Bank 2 code! Replaced both down stream 02 sensors last week and now the code comes on within a few minutes of being cleared! MAF has been cleaned, the intake gasket was replaced when the motor was installed, and can’t find any loose vacuum lines!
So I’m down to a fuel issue or the air fuel sensors! I have the intake, fuel rail and injectors off my old motor and thinking about swapping the injectors out, before spending the $300 on air/fuel sensors!
Any other ideas?
