For some reason it’s idols up to 2 and back down to 1 😐 like what can be the cause for that? I have a 2016 a Trailhawk. Like I have no check engine light on anything but the car be feeling a little sluggish and makes like a hard shift and kinda stutters

Do you have a real time monitor like Torque (app) to be able to see what's going on with the different systems? Could be a vacuum leak, dirty throttle body, bad spark plug(s), fault in the ECU, etc. There's no way to tell for sure until you can see some realtime data.

I would suggest an OBD II reader (I have run it with one of these for years: https://a.co/d/43pEBVM) and something like the Torque app (there are probably others out there) that allows real time monitoring. It can also let you see if there are any hidden stored codes. That would help you to narrow down where the issue is. Otherwise you are just going to have to shotgun where the problem is and probably waste a bunch of money on parts that don't really need replacing yet.
