I've cleaned the ICV on my 1990 C2 as discussed in this thread using brake cleaning fluid (although apparently some think this could lead to corrosion of the valve). Now my 964 maintains a reasonable idle and hasn't stalled at stop lights, etc. like it did previously. Still, ideally it would idle with a little less RPM fluctuation when I first come to a stop.

I was wondering, is there any reason it wouldn't make sense to lubricate the ICV with WD40 or some other lubricant? Would this potentially attract more dust and grunge and make things worse? Since it's a moving part, some kind of lubrication would seem to make sense.

Great thread B.T.W., it's already helped me improve my car's idle substantially.
