Welcome to the forums.

There are some good mechanics checking in here but you may also want to check out the actual clubs.... like the Jeep owners forums.

From my limited experience with drive-by-wire systems..... a dirty throttle plate or throttle bore can cause all kinds of issues. You could also have a work throttle position actuator. Unfortunately.... these parts are expensive to just throw at a repair.

This video shows what a clean throttle position assembly looks like.
