I had this problem happened to me 2 weeks ago. When I cleaned my TB, I accidentally push some carbon onto the screen of the IACV and the idle was really high. Cleaning that out fixed it. When you sprayed clean the idle screws, you must have free up some air space and making the idle higher or the screw might be backing out slowly when you cleaned it. Notice the position and if needed turn it it in slowly. Better yet, just adjust your base idle again by pulling the IACV and see where it is. Colder weather does make the car idle a little higher but 50 rpm isn’t that high or bad. But with the car idle over 1000 when not in gear is similar to the problem I had 2 weeks ago. I just spray clean mine without even taking the coolant lines off so no need to bleed the system after.
