New to the forum and hoping for some answers.
I bought my first Jeep, a 2015 JKU Sport (6 speed manual, 63000) ,back in September 2021. Since then i have encountered several issues running the gambit from the oil cooler housing leaking to the radiator leaking to changing the clutch. My current issue has me stumped.

I have noticed a major problem starting out in first gear and reverse with a rpm drop and then a stall. I've been driving manual shifts all of my life and i haven't stalled this many times since I was 16 with my first stick shift. I notice the rpm drop in 1st gear mainly but reverse stalls out a lot too. I've also noticed its a dog going up any type of hill.

Reverse is whole different story. Over the weekend i had a small utility trailer behind me with a slight load on it. I had to back up a small grade and i barely made it up. Between stalling 5x and having to rev the rpms to around 4000 just to get it to move, i'm sure i burnt up a little of the new clutch i put on about 2 months ago. I've had the same issue with an empty trailer as well- the Jeep just does not want to push it up a grade.

I've changed the MAP sensor, CAM sensor, and crank position sensor and nothing seems to work for me. I'm starting to lean towards an emissions issue but i don't want to just throw parts at it. Any help will be appreciated.
