Hi there
When I start my p11 the idle is surging between 2k and 3k. It setlles down after driving and seems ok trough the rest of the gears but when i stop and start again the same thing happens. Any ideas what this is??
Any help would be greatly appreciated

AAC valve is sticking by the sound of it.  try disconnecting it and see if it improves .... you may need to rev/blip a little when it's cold btw.
 
just unplug the brown plug in the pic below ( shauns pic that I stole Embarrassed )

Your "other car" might be newer, but it don't make it better than a P chassis.*PNP17*

Thanks for the help. Did what you said the idle shot up to 3500 rpms on start up reved it a couple of times and the idle dropped back to just under 1000 rpm and stayed steady.Is this what you'd expect to happen ?? Do I need to replace the throttle body ???
Dont know much about car engines only what I learn when things go wrong.

Just looked at it again. I take it I need to replace the valve not the trottle body. Is My description of what happened when I removed the plug point to IAC or something else? As you can tell Im a real newbie when it comes to engines.Thanks again

Ok a quick update I've Just relised My car is a p11 144 and that Ive probably posted this in the wrong section. Had a look at the factory service manual Thanks to ever posted those there excellant. I found the section on Idle controll valve learning and carried it out.  It seemed to work the Idle dropped to the correct level but after a number of restarts the idle had risen to 2k and started surging again. Repeated the procedure with exact Thanks again.
