P0171 code
Getting this code, too lean. Typically this would indicate MAF or o2 sensor. But could be a fuel filter too. Car is a 2004 Kompressor. Less than 100,000 miles on it. Suggestions what to fix first? Appreciate input

Check all your vacuum hoses etc.
and look for any leaks on the intake side.
I pulled my hair out on this one.
I think in the end, it was the MAF.
A better code reader is useful.SDS is best of course.
I had old Carsoft 7.4 and it came right up and said
problem with MAF. Sadly it doesn't work anymore with newer computer.
But I found cracked hoses too.
