Thanks in advance for all your help. When I have my car in park position I notice that the idle is slightly moving up and down from 500rpm maybe 10-25 rpm give or take. But when I am driving and come to a full stop it’s steady at 500 rpm and not moving up and down. Any thoughts on this.

Check filters and spark plugs. Check for vacuum leaks. Clean throttle body and MAF sensor. Perform a full diagnostic scan for codes and live data.
