Terra, the wd40 was discussed as a lubricant, not cleaner.
Now that you mention it, I might have used TB cleaner for the ICV. I have too many posts to see what I used, as it was a while back, but have since learned that brake/parts cleaner is very aggressive, so wouldn't ever use that on anything like disa, icv, tb, or anything electronic.
I don't know what lubricant would be best, and I can't imagine that any spray would really last for a particularly long time with air getting blown over it constantly.
I'm so depressed. No one wants to come see me in NYC: Sat, Oct. 8, 6 p.m. at Greenwich Village Comedy Club.
Mangofy your E46!
