2010 Chrysler T&C touring 3.8 Rough Idle

Just wanted to see if anyone might have some advice on where to start trying to smooth this thing out. I recently bought a 2010 T&C with just under 200k miles and below 1500 rpms runs kinda rough but when idling is when it's most noticeable. No CEL or throwing codes, occasionally will hear a whine while coasting downhill but as soon as I give it any gas it goes away.
