DTC P0174 : Fuel Deliver System : Air/Fuel ratio is correcting rich for an overly lean condition
Possible causes are:
EGR system faulty
air intake or vacuum system leak
engine oil leveltoo high
excessive internal engine wear
fuel system malfunction
first to test would be the oxygen sensor(s), they are the easiest and cheapest to replace if needed.
