I am currently helping a budy work on a 2011 and a 2015. Both bone stock other than being right hand drive from "postal petes" jku v6s 3.8/3.6 automatic sports the 2011 has a misfire on #3 the 2015 has misfire on #1. Plugs, coils, O2s, and injectors have been changed. After clearing codes will run and idle fine until you are in drive and accurate, at about 4,000rpm both get their same misfire that doesn't quit until codes are cleared again. You can drive them all day long if you keep rims under 4000ish without issues.

at least on the 3.8l ,2011 , it is not a small detail which - specific- ,"Plugs, coils, O2s, and injectors have been changed" you changed them to.

those details are important .

use of anything other than the boring old Champion plugs & Mopar ignition wires can be wonky.Injectors can have orings issue (s) , O2 sensors can muck w tunes ...

more details , specifics & codes being thrown or it's nearly useless to try to sggst anything.
not to mention , while symptoms are similar on both jeeps , an 11 JK & a 15 JK are 2 very different jeeps .
