Help, what does this mean?!

Yesterday I got a check engine light. I went to Autozone and had them read the code. It came back with code P0171

The PCM has determined that during testing, the fuel system for bank 1 was too lean.

Any ideas? The guy at Autozone said it could be an oxygen sensor. Thanks.

do you have any mods? sounds like that would be the problem unless you fucked up some wiring.

No, it is all stock. Is there anyway to tell which o2 sensor it could be? Is it more likely to be the first one? Oh, and I haven't noticed any decrease in performance.

bank one is the first one.

what about a dirty MAF, I read about some issues with them on the 00's. I am going to try cleaning it. Does anyone know where it is located?

Cool. I don't plan on taking it in to the dealer as long as driveability is ok. I have a feeling they will try to screw me. Anyway I cleaned the maf and reset the ecu and the light has gone off, hopefully it will stay that way. Thanks for the heads up on no problems with your light so far.
