Don't count out a vacuum leak either. Pretty sure that's why mine wanders, at least.

update
I sprayed some sea foam into the intake tube running to the ISV and then pulled the elctrical connection of the ISV and shot that with some sea foam lube...idles perfect for now

What is this "sea foam spray & sea foam lube" you speak of?
& where do you get it, my idle also hunts when cold & I have not been able to find ANY vacuum leaks.
