Something loose underneath that vibrates only while idling?

Hm, I shouldn't need to clean the TB already, only has 33,000 KM on it (2017).
I used to do this monthly on my 2000 Grand Cherokee that was at 200,000 KM before I bought the PF.
I'll take a look though.
Are you able to see recordable misfires? Has the check engine light ever come on?
I doubt it would be throttle body related given the 2017+ use direct fuel injection, but a TB cleaning couldn't hurt.
Once the upper intake manifold is removed for a spark plug change out, id be interested in seeing how dirty the back sides of the intake valves are and if they'll need walnut blasting like lots of DI engines need from time to time.
Super carboned up intake valves could cause misfires.
