Exactly what has the dealer replaced or repaired?P0174 lean exhaust bank2..?With the 4.6 motors...MAF getting dirty(oil dirt)...clean it using an electronic cleaning spray....bad MAF...Intake gaskets leaking....Exhaust manifolds leaking....etc....could be a small vaccum leak..those plastic gaskets under the intake are the most common....

could it be a 02 sensor?

i'm curious to see what they did for $2600 dollars. becuase i tell you what if its not fixed after that they need to fire all there tech's and higher real ones.
possible causes, bad 02, clogged injector(s), intake gasket leak, possible crack in the intake on the one bank.
I wish your car was here i like fixing these problems. and with the new scan tools we have at my dealer it tells you so much info on everything the car is doing it makes fixing these problems so much easier.
