I have a 2012 ram 2500 that is deleted with the raceme ultra I have the egr unplugged with about 90000 miles on the truck. I was at a stop light the other day after driving for about 30min and the check engine like came on so I ran the code reader on my ultra and it showed the code P0191 I tried to clear the code but it comes back immediately what could possibly be causing this issue?
