fix one thing now another...

so i got my car through isnpection and fix the catalyst deficency code with a magnaflow cat. i havent had a CEL for about 500miles and all my I/M sensors have checked so i know its not gonna just come back with the previous code. now just driving to my friends house last night the CEL comes on, ok i scan it and comes back with P0171, lean bank one but car is running fine.

just doing the bit of research online ive learned to check vacum lines for cracks, inspect MAF, change upstream o2s.

this is what has been done in past year as far as maintence and mods, k/n cold air (installed 4 months ago), new rear o2 (1 month isntalled), magnaflow highflow cat (1 month isntalled), new ac-delco factory spec plugs and wires (12months installed), pacesetter header (with an exhaust leak, installed 12 months). new oem fuel pump and filter (6 months). the car is a 02 camaro 3.8l with 98k miles. obviously checking vacum lines are easiest thing to do but what else should i look out for?

thanks for your help
