I can't get the idle speed below 1200rpm. There's no more adjustment left on the end-stop on the throttle cable linkage, and the cable is slack when the throttle's closed. Is there some other adjustment I can make? Haynes doesn't seem to mention it...

There is no idle adjustment on any E30, or any other car made since about 1990 for that matter. Idle speed is controlled by the ECU.
Put the throttle stop back where you found it, never touch it again, and look for the air leak.

Thanks Brian. Will have a look. It's been suggested the ICV may be faulty - is this likely?
318-is thanks for the advice, but I think I'll hang on to the manual what with it being the one for the M42.
