Here’s the jeep FCA TSB 18-028-06.
It will, like it did me, possibly drive you crazy.
P2098 will no doubly raise its head as well.
Main thing for me would be (importantly) check for exhaust leaks especially around manifold.
I’m not saying you won’t solve it, but I did 4 x O2 sensors, cleaned TB, checked exhaust leaks, replaced sparks, replaced sensors on TB, made sure I was only using 91ron, fuel filter, new gas cap, and I think much more ..... I solved it. But it came back three months ago !
