I thought Walla was an expression of the desire to wear muffintop jeans and t-shirts one size to small whilst shopping at Wallyworld.

Oh !@#$%^%$! the idle adjustment screw broke/stripped. IT is the flathead screw driver type or was. I was being very careful too. What now? I did a search but came up with nothing.

that makes sense.
i have been meaning to pull the ICV on my 88 BMW and do some tests on the ICV.
i think this is a very missunderstood device and often blamed for problems that are not its fault.

On the throttle body it has 2 idle adjustments:
1 - the Air Bypass screw in the center of the TB
2 - the throttle plate stop screw on the left hand side

Which of the 2 did you break? The Air bypass is not turned with a screw driver, you use a small socket to adjust it (I think 8mm?)

No matter which one I recommend removing the TB from the intake, it's not very difficult and it will be far easier to repair on the bench.
