P0171 and P0174 are lean fuel codes - P0325 is a knock sensor code. Ignore the P0325 for now, as it may be related to the fuel issue. Look for vacuum leaks with the lean codes. Specifically - on this engine - if it's the SOHC 4.0L V6 - it is notorious for failure of the intake manifold o-ring gaskets. I would guess that the leak is there.
