Hi, recently my 2015 Genesis coupe V6 R-spec MT has been revving on it’s own whenever the rpm’s are dropping. It can be from me using 1 and 2 well driving through a parking lot, as well as im getting off the freeway or getting to a stop. I’ll put it in neutral and apply the brakes and as the rpm’s drop to 1000 the engine will rev up on its own usually up to 2000 and then a sudden drop. When warmed up my rpm’s sit in between 1 and 0 in the odometer. Can someone please give me some feed back, I would really like to get this fixed before it turns into something big. Please help.

I would try cleaning the throttle body. You can try manually opening it and spraying at the pivot points but removal and hand cleaning may be the best.
