Engine Codes

i just recently changed the clutch and flywheel in my 03 gt 5 speed and i keep getting engine codes that turn on and off. i used my scanner and got 4 codes: P0171 fuel lean bank 1, P0174 fuel lean bank 2, P1166 Lambda bank 1 control limit, P1167 lambda bank 2 control limit. does anyone know what these codes mean or a site that knows what they mean? any help would be nice since i got emision testing this month

hmmm i couldve sworn i saw this on a thread before, i mean a list explaining all the codes, id try running a search on this site, and if nothing comes up go to Newtiburon.com and that may be where i saw it.....Besides that, sorry man im clueless
