Do you have any codes or engine light on? Is the Jeep running poorly?
You can try cleaning first.
IAC- See post #10 onwards.. https://www.jeepkj.com/threads/idle-air-control-no-screws.44826/
With the Jeep parked (off) it is easy enough to spray some carb cleaner into the intake, by opening throttle plate, to clean things up.
Expect the IAC & the interior port to be real dirty.
Tps port generally is not too bad.
I eventually replaced the IAC and TPS with Mopar parts.

Thank you!
I read more in the FSM and it looks like if I do the IAC/IAT/TB/MAP/TPS I may as well do it all at the same time.
You recommended carb cleaner to clean the parts, and grease for seals?
I only use carb cleaner on the IAC and Port as Throttle body cleaner is not strong enough.
As long as a throttle body is not Teflon coated, it is ok to use carb cleaner on the aluminum intake.
MAP & MAF sensors be careful how you clean them and consider MAF senor friendly cleaners, don't soak them.
I use silicone spray for seals.
