You didn't mention the year of your car so I'll assume it's not DBW.
Did you measure the TPS voltage at idle? I know you changed the throttle body, but that doesn't mean the new one is working properly. Since you mentioned it does not rev smoothly in neutral, I would put a meter on the TPS and make sure the TPS voltage smoothly increases as you manually open the throttle by rotating it from under the hood.
Have you checked for a vacuum leak?
