Idle seem to be a bit smoother at cold Start, and have not had any issues or even slight hesitation during warm starts as I had pre-cleaning. This seems to have addressed the problem, and will likely need to become a regular 30,000 mile maintenance item. Thanks for the tip Debonair!
Awesome! Glad to hear it's running better.

So everything is good?
On cars with cable operated throttle bodies you could just flip the butterfly open and clean it real easy. With motor operated throttle bodies you should be a little more careful and in my opinion not to force it open. Some people still force it open with no issue, just like some people unplug it with no issue. Other people force it open and have issues. And when it's unplugged sometimes it has to be relearned using the air volume relearn procedure which can be tricky. So cleaning the front and back without unplugging it or forcing it open should have no negative affect on it.
A clean throttle body is actually pretty important in my book. It was actually the first bit of maintenance I did to my car when I bought it since there typically is a 99% chance it has never been done.
