Maybe a dumb question, but what was the outside air temperature when you saw the smoke? I've never really idled the D at cold temperatures often/long enough to make a note of the quality/quantity of the exhaust but in my other car (87 CRX, carburated, ~280k miles), I've noticed the exhaust is definitely more visible when idling high in cold weather after a cold start. I'd always assumed that was standard car behavior?
The WUR and the idle speed motor were next on my list to check out (when it was just a rough start issue)!

I'm in Texas so it wasn't cold... it was probably about 85 outside. When I say "white smoke" I don't mean like... a little. I mean... I couldn't see my neighbor's house.
