It is very likely that an ECM reflash will be necessary to resolve this issue. When the ECM gets replaced, the vehicle essentially loses all of its memory. The reflash will program the ECM to your vehicle allowing it to drive properly. I would recommend consulting with your local Dodge dealership to determine if the reflash service will be necessary to fix this problem.
