I have searched on here for a while and cannot find the answer to my problem. I have a 2008 6.7, exhaust delete, egr delete, cold air intake, smarty junior. I had to replace my batteries about a week ago and since hen I have had a check engine light on that will not go away. I have tried to clear them a few times with no luck it comes right back on. Before the battery change it never came on. Please help me out with something I can do to clear it for good.
