2017 Kia forte LX idles rough sometimes?

About once every 2 days at a traffic light my car idles rough for about 7-8 seconds to the point where the cat almost shakes. Then it goes back to normal running perfect. My car has 64000 miles so I went ahead and had the spark plugs replaced. Still the same.

    Clean the throttle body next.
