I suspect we have an issue with the throttle position sensor. There are a number of things that can cause this but since you cleaned the throttle body, I think you damaged the sensor, and it is now causing this issue.
Here is a guide that will help with this issue in case the position sensor checks out okay:

However, based on this info I suspect this is what we are going to find.
I would suggest starting with checking the codes and go from there.

See the attached info and that will help with determining if this is a position sensor. We can try and relearn the idle, but I doubt that will solve it so let's run through this and go from there.
Thanks
