Not quite so simple as it is made out to be.
At times the idle speed changed both cold and hot. Not a lot, but it should not be so.
The Air flap opened and closed ok .. but the was a build up of krud around it, and looking down inside at the Butterfly , it had a build up of carbon like krud around the edge. Circuit Board cleaner, cleaned it all up ( I didn't have anything else ) Now a nice steady idle cold at 1000 RPM. So hot should be ok at around 750 RPM
(providing the Auxiliary Air Valve is doing it's job)
