Durango Discussions
I have a 2007 Dodge Durango 4.7 flex with 320,000 miles. Recently I have had the issue where it runs rough when I start it. I have ran the codes and there are 6. P0420, P0457, P0456, P0300, P1128, and P0440. If you let it idle for around 3 minutes before driving, it runs just fine with no issue...
