Had the same issue, turns out after doing a tune out that the cam shafts is bad resulting in the misfire. Turns out this is common in rams due to the fuel conservation (eco mode) while on the interstate where 4 cylinders shut down automatically to conserve fuel. Apparently over time, it wears the cams down and develops a misfire. Very expensive fix.

My 2013 Ram lately has been getting bad gas mileage and notice the eco light doesn’t come on any longer. There is check eng light but this is due to ambient temp sensor being out. I was told there may be connection under seat that could be issue. Reconnected every connection under both seats. Need help.
