Does anyone know what the resistance between the ICV's two terminals should measure as? I just got my multimeter on there and got a value of 8.3 Ohms. I thought that I read somewhere that it should be ~20 Ohms, but I cannot remember. Thanks!
Alternatively, if someone could run out and check theirs with a meter, that would be appreciated too!

Somebody correct me if I'm wrong. 3 terminal 40 ohms between two 20 ohms between the other two, 2 terminal- between 8 & 10 ohms.
Stick with it bmwman91 you almost got it, they don't make um like this anymore.

Thanks, yeah I am getting 8.3 Ohms. Where'd you see that spec?

Note also that the ICV is not supposed to buzz (like it does with other E30s):

Interesting, thanks. There's one less thing to worry about then!

Those numbers came from the Bentley book but mine covers 1984 thru 1990 not the m42. I looked to see what my 95 m42 spec is and haven't found it yet.

Well, so far all of my idle problems are gone. I filled a cup with 99% isopropyl alcohol and let the ICV sit in there for a good couple of hours. Then I dumped it out (a lot gets up into the body) and poured more alcohol through it and shoot it around. After that I stuck it in a thermal chamber at 65°C for a few hours to fully dry out (yeah I may have been doing this in the lab at work lol).
The alcohol turned yellowish and all sorts of black dust/particles came out of it. I bet that all of the oil blow-by and vapors in the PCV system, as well as whatever crap blew back up my intake when the valve spring broke, gummed it up real bad, and then it sat for 4 months. After this thorough cleaning, it idles brilliantly. I can tell it is a lot cleaner because with just a light shake of the ICV I cna hear the door moving inside.
