i'm not sure about the autozone scanners but i'd definately scan it first before you replace the o2 sensors cause last time i priced them they were about $45 a piece! did you also put in an offroad h-pipe with your headers? cause thats what would be giving you the check engine light, if this is the case theres something you can buy to plug into the sensors to fix it, MIL eliminators maybe? good luck, Drew
