I would pull the radio fuse (7.5 amp) in the underhood fuse box to reset the ECU, so it can relearn your idle settings.

Did you scrub out the throttle plate area with a steel wire brush?
What might have happened, is some crud broke loose in the air passages and is sticking in the IACV.
Might be worth the effort to pop it off and blast it out with carb cleaner and compressed air.

blue smoke = burning oil.

the idle problem after a thottle cleaning is most likely a disconnected vacuum line. check that all the vacuum lines are secure since you disturbed the intake tubing which has vacuum lines secured to it.

The smoke might be the burning of the hydrocarbons in the throttle body cleaner you sprayed into the plenum (so the engine will briefly run effectively as if it were rich because of excess burning hydrocarbons i.e. cleaner plus petrol). There's also probably carbon from the muck you cleaned out of the throttle body coming out the exhaust pipe.

it's possible...but i've usually seen black smoke from throttle cleaning, or white smoke. our shop recently started using a valvoline fuel system cleaner(liquid drip, injector additive and throttle cleaning. the car smokes WHITE for 10-15 minutes after...i don't like it. [>:]

What about; if the inside of the plenum were caked in half dried up oil from being sprayed with oil from the crank breather hose for years, the cleaner could have softened this to the point that it's slowly running off the plenum walls into the cylinders?? Just thinking out loud, might be barking up the wrong tree.

i hear ya man! forum = theory while real life =practice. it's very difficult to try and fix some things without being in front of the car watching it react to you actions. lots of good info

Did you check your brake booster hose?
