First of all.

Great post.
My IACV is a different type than the one depicted in the pictures but reading through this post was very helpful for me as an inspiration to clean my IACV :-)

I am new in here and may be a slight misfit.. Driving a Legacy and living in Europe :-) But I feel I wanna add something here.

The IACV is the unit found on top of the throttle body right after the air filter.
it's the one with a blue label in the picture.

I just cleaned the IACV on my 2000 Legacy Stationcar.
I used alcohol and cotton swabs.
I took some pictures with my phone and if anyone wants to see I'll upload them somewhere.
On this model there is no need for any gaskets. There is a small rubber ring on the IACV and that should be reusable.
However, be careful with the screws. I used a flat-head screwdriver as mentioned in the first post. The screws were quite stuck so I soaked them in WD40 for a while before being able to loosen them without using too much force.

I can recommend the job!
I have only had very short trips in the car since I did it so I am still uncertain of the actual outcome but I do believe I gained not only better idling from it.

I was feeling lots of vibrations in the car while idling, the rpms would stay solid (most of the time..) but I would still feel the car shaking a lot.
And when driving at very slow speed only lightly touching the accelerator in first gear the car was prone to skip and jump a bit much.
When releasing the foot from the accelerator the engine would drop to very low rpms before picking up again and settling on the idle level of approx. 700rpms.
I believe that cleaning the IACV helped on all above mentioned issues.
Maybe it didn't quite solve the vibrations while idling but I can't really say until I have had a few more trips in the car.
