How would you rate this car

2001 ranger 3.0
I have codes p172 and p174
I believe it’s from fuel too lean .
MAF sensor appears ok, replaced pcv valve
Passed a smoke test . Fuel filter replaced last year.
Can anyone tell me what my next steps should be?
Truck runs perfectly . Idle is steady.
Nothing indicates something is wrong yet I can’t stop codes from popping .
