Please help p0420 and p0457
I'm getting a p0420 and a p0457 on my 2005 2500 hemi ram... I only get them together never separate .. I know what both mean just wondering if there related... I've put all 4 new o2 sensors and and checked my gas cap and its good.. Has anyone done a PCM re flash for this issue...
