Hey folks, I have a 2021 JLU with the 3.6 e torque. Every now and then when moving the Jeep at idle, low rpm, the engine will die. Anyone else have this issue? I've tried searching. Seen a lot of stuff on rough idle. And something about fuel air ratio at idle. Looking for a solution. Any help is appreciated.

Plug an OBD-2 scanner into the OBD port, see if anything shows up...

Not nearly enough information to go off of here.

Operating temp at the time of the concern?
Oil level?
Have you been ignoring any warning lights?

Usually happens at cold start up, so oil temp is ambient. Oil level is good, halfway up dip stick. No warning light till it dies then throws P1C64. It has reset itself on a long drive. Doesn't have rough idle. I have read some posts about possible fuel/air mixture at idle. Just trying to see if anyone else has had this problem and solution of course.

I've seen post about reflash. It's weird, it's not happening at restart.
Thanks
