Idle is rough when my car is at a light or is parked it seems like they idle just goes up and down a little bit not too much where it's annoying but somebody noticed that it's kind of almost like there's a vacuum leak a little bit but I'm not sure if it's normal I haven't had it before so if someone can share what it could be it'll give me a little start

 

Do fuel trims checks. Will show any leaks.

 

You will need to check the codes and see what the car is telling you.
