Aux Air valve

Well the fast idle is solved - and possibly the reason for the original melt down in the engine.
The AAV was not working and rested in a half open position.
A combination of bent finger and detached thermo wire internally.
In exchange for all the info you guys have provided, for what it is worth, if useful, you can fix these beasts, and the WUR. This is the second AAV I have had apart now.
Just drill the 4 pins out - drill the heads off, and push the pins out.
Then you can do what is required, in my case I straightened the bimetallic finger - you can set the opening slot to where you want, and soldered one of the heating wires back on its terminal. (Only ponder whether solder is good enough. If it comes off again, the car will lean out again).
It is a different car and idles properly now.
Still working on my lack of wiring and surplus of sensors.
The probe blanked off in the exhaust it transpires was a temp probe - connected to a light on the dash - required for Japanese models apparently. Altho I am sure this car was not Japan new. Also disconnected/removed.
Regards
Alan
