so you're down to 2 choices.
1. use it like a car, only hauling a few bags of groceries.
2. trade it in on that Prius you been dreaming about.

replacing worn injectors with new ones with high flow rate nozzles can also cause the fuel rationality ECM algorithm code problem.

this may have been Fiat Chrysler's way of solving all their still on the road engine warranty issues with the 5.9 HPCR caused by add on boy toy programmers damaging their engines. The Fiat software developers came up with the 5.9 ECM Bug from Hell.
