RPM too high after driving or WOT

I had never seen this before in a drive by wire throttle body vehicle, but after a while of driving and putting my car on neutral or park my rpm will hang around 1000 rpm. This also happens when I WOT and come to a stop. When in gear, it also seems high probably around 800 rpm. I shut the car off and idles fine again once I restart. I have also managed to bring the rpm down by turning the steering wheel full lock, which I guess adds load to the motor, but sometimes it will go back up.

Think I have a bad throttle body?
I have cleaned it with same results...

2009 G8 GT SRM, OBX Catless Long tube headers, DOD Delete, LS3 stock cam, tuned with HPTuners, Atari gauges.
