Check engine error code PO174 - 2001 Ford Taurus

A PO174 LEAN CODE FOR BANK 2 IS THE CYLINDER BANK ON THE LEFT SIDE OF THE ENGINE
(THE CYLINDERS FACING THE FRONT OF YOUR CAR)
A LEAN FUEL CONDITION COULD EXIST IF THE ENGINE IS GETING
TO MUCH AIR AND/OR NOT GETING ENOUGH FUEL
THIS CAN CAUSE MISFIRE, ROUGH IDLE, AND HESITATION WHEN ACCELERATING
THIS COULD BE
A VACUME LEAK, A DIRTY AIRFLOW SENSOR,
A EGR VALVE NOT CLOSING LEAKING EXHAUST INTO THE INTAKE MANIFOLD
IF ITS NOT GETING ENOUGH FUEL THE FUEL PUMP COULD BE BAD, THE AIR FILTER COULD BE DIRTY
OR IT COULD BE DIRTY INJECTORS
ID TRY FUEL INJECTOR CLEANER AND A NEW AIR FILTER FIRST
THEN TRY CLEANING YOUR EGR VALVE. COPY THIS LINK TO YOUR BROWSER FOR
STEP BY STEP INSTRUCTIONS TO DO THIS.

IF THIS DONT DO IT I WOULD TAKE IT TO A MECHANIC TO HAVE THE OTHER THINGS CHECKED
HOPE THIS HELPS.
