I'd be replacing the throttle body housing and inlet manifold. The whole set-up will be around £40.
I had a 206 in last year which had the very same problem. Previous mechanics had replaced Map Sensor, idle control valve, AFM, cleaned the inlet etc, and 1 even went as far as replacing the ECU and key reader. It turned out a guy had serviced the car and knew about the problem with the build-up on the inlet, so he cleaned the throttle body with a screwdriver and a rag with a drop of WD40 while servicing the rest of the car, which ended up in a few fine/tiny scratches in the inlet meaning a small amount of air was getting past the butterfly flap. A slight oversight on his behalf (a fine screwdriver with a rag on the end of it can be ideal for some applications, but not this 1) which cost the owner hundreds.
While we were at it, we replaced 1 of the sensors on the throttle body too, as it was also a known fault in that model, but the car ran fine instantly with the new inlet and immediate gaskets replaced
