2012 Dodge ram with 208,000 kms. For the past year randomly around 1000 to 2000 rpm and 5th or 6th gear with MDS deactivated it just won't rev or build power be eventually it will drop a gear and about 10 to 15 seconds later just take right off. I bought a Blue Driver scanner tool. No check engine lights come on. Replaced air temp sensor and map sensor. Cleaned throttle body as well as swapped throttle body with my 2010 2500 and same issue. Noticed recently that I have a live mode on the Blue Driver scan tool and noticed when issue starts the fuel system goes into open loop and tool shows that I am at 100% engine load. This happens on level road or slight incline most of the time. O2 sensors seam fine. I have tried with MDS enabled and disabled with same outcome. I get no misfire counts on any cylinders. Looking for any kind of help. I took some screen shots when it acts up for you to see.
