As some of you know I have Alldata and can provide tons of info. If any of you need anything feel free to PM me about it.

I have gathered all B/C/P/U 2004-2006 codes for the 5.7s liters.

This site will give a pop-up every once in a while but it is a site that will not go down, give you a busy wait number or run out of downloads and its free.

These are in PDF and give everything you will need and more
