Hello all,
Coming home today the dreaded 'bing' of the check engine light caught my attention and checking the code with the 3 key turns, I got the code P0171. Does anyone have info on this code and what needs to be done to correct it? Is this a DIY fix or a (s)dealer fix.

BTW, it's a 2002 model (if needed).

Thank You for any info.
