throwing lean code

my car threw a lean code P0171 (bank 1) and lean code P0174(bank 2). i was thinking maybe my o2 sensors are failing?

could be fuel filter, maf needing cleaned, or a few other things but thats where I'd start.

I had those same codes for a long time i cleaned the MAF twice and they went away for a couple weeks but would come back. I had 20 bucks sitting on my autzone rewards card so i bought a new MAF and no problems since but try cleanin it first.

Re: throwing lean code

oem stuff can be very over priced and over rated. go to an autozone. most of the time you will get a warrenty with their products.
