When mine gave me the same codes it was my CAI filter. I over oiled it. So don't start replacing part after part and try to trouble shoot it before spending a bunch of $$$$$. As mentioned before my post. It has something to do with air delivery issue. Those codes a real generic and just saying that by the time the air reached the 02 sensors it failed. Good luck and don't give up.
