Hi Joel,

Nope.  Mind you, I haven't looked too hard either -- it doesn't
prevent me from getting where I'm going!

My best guess right now (and I do mean a guess), in no order:
-vacuum leak
-flakey idle switch
-flakey idle computer

I get high idle (1800 rpm) on first start-up and it stays
above 1000 for several minutes.  I also get ~1800 rpm idle
very occasionally when driving with warm engine too.

I checked for click noise from idle switch, cleaned contacts
on idle computer, and checked for buzzing from idle air
bypass.  Also when I unplug idle air bypass, idle speed
goes down so it's definitely related to the idle circuit!

Is this what's happening to you?

Good luck,

tabe
