2016 renegade latitude idle question

I have a 2016 2.4 latitude with about 78k miles on it. Just about a week ago I've noticed when im in drive and completely stopped, the idle seems to be shaky or maybe even stuttering? Im not sure how to describe it. When I accelerate it'll make a noticeable growling noise that goes away once I get to about 20mph. Not sure what it could be.
