bad idling

[As One]

Hi guys,

maybe some of the engine experts might be able to help...

The idle has gone funny on my 88 911 3,2. When warm it revs up to 2000 @ idle. It is not the idle control valve, so I assume that it is the air temp sensor.

I believe it's wiring loom is located on the lh side of the engine bay, however I do not know which plug (of the 3) it is. Also I dont have any data ( re its resitance and feed voltage) about it. Where is the actual sensor and how easy is it to replace anyway ?

Any help greatly appreciated - thx.

Regards,
Felix
