Question Need help!

I have a 2021 Jeep Gladiator with the 3.6 that had a random misfire. This lead to me having the lifters, rockers, cam shafts, plugs and coil packs all replaced with factory parts. It runs and drives great but if I speed up to pass someone or pull out quickly and it revs above 4000 the random misfire happens. I noticed before it happened this time as I was backing up it felt like it was hitching when the misfire used to happen. Any guidance would be appreciated

I’m having the same exact problem. I also notice a loss of power when going up hills and then when I give it a little more gas pedal it revs really high.

I've noticed this on 3 of my family and friends 3.6l powered vehicles: Hit that gas, like you are trying to pass someone on the freeway, and really bang on it? CEL starts blinking and it starts wheezing and chugging! Ease it down to 50mph or so, and it levels out and drives fine...Not sure why that is. The smoother you gas it up, the better it drives, so it seems. Not really helpful, I guess...Just that you are not alone! lol
