i have the same problem, and also, i called an auto tune up company who can out and paid them Ԛ£30 to tell me that the car has no o2 sensor or has a fault with it when the car never came with one?? im gettin a new engine loom and going to bmw to get a new connector thing for the injector loom and see if that does it.

i would replace the ICV and be done with it, thats what i did and it fixed the problem

Check ALL the intake pipes mate.
Had all sorts of trouble in the past usually resulting in a bad idle. Was someone here...Sal i think suggested it and i checked all the rubber bits. Solved the problem and got the idle back as it should have been.
Good luck fella,
Nick.

Check your fuel regulator that is located near your N/s rear wheel as these get badly rusted and worn drawing air in with the fuel causing poor idle,also take theICV off and clean it with carb cleaner as they are Ԛ£70 a time and replacing is expense when they last longer than a year
