Default Idle wandes 500-700 rpm

I have a new to me 2008 V6 Sonata with 76000KM or 43000 miles. It drives excellent but after warming up the idle wanders between 500 and 700 rpm.
Could that be plugs???

It is sometimes fuel related
If you have a MAF then clean it
If you have an IAC or ISC then clean it
Get injector cleaner and clean the injectors

And wife is always right ... even when she is wrong ... lol
