cleaned ISV valve. now car stalls
First, I should say that I've renewed my membership and am waiting to get me member status back.
I cleaned my filthy ISV with brake cleaner and bolted her back up. Now she stalls while idling. I'm pretty certain I didn't knock any vacuum lines loose. What do you guys think?

Hi Shafo, my first tought goes to the correct connection of the ISV. Is the arrow in the good direction? I join a picture which is a blow up, I hope the arrow is visible on it..

I had the same problem after the first attempt at cleaning the ISV ; after a thorough clean, it should rattle with a sound similar to shaking a paint can. Only then is it thoroughly clean with the inside surface in a silver color.

If yours moved freely after you cleaned it, then yes, recheck the connections as JP and Bob recommended.
Good luck. Let us know what the results are.

If it is working properly, your idle will be rock steady as it accounts for variations. If it is sticky/stuck, the idle will be high/low/erratic. A great side benefit of a properly functioning valve is easier/better modulated take off from a stop.
How often to clean? Depends on how much/how you drive the car. In my experience, about twice a year keeps the car nice and easy to drive. If you think your clutch take up is hard to engage smoothly and that something might be wrong with your clutch, it might be the ISV needs cleaning.
If you've never cleaned it, try it... it will give you a good baseline for future cleanings.
Good luck

If you forget to hook the electrical connection back up, it will probably stall on idle, and in addition your CEL will be on (if it wasn't already). Don't ask how I know.
When I cleaned my ISV the first time, it was so caked up that i had to re-read p-car.com and Kelly's posts a second time to convince myself it was supposed to be able to move! I ended up having to (carefully) use a screwdriver to break it free...

I just found the time to take another look at it. It is in the proper orientation and the connection is in place. I don't remember it being able to move, though. I'll take it out and coerce it gently into movement.
My only nightmare is that I damaged the hidden, rubber portion of the aft tube while manhandling the isv into position. Is there a trick I'm missing to make it's reinsertion/connection easier?

Don't use anything containing silicone anywhere on the engine unless the product says, "oxygen sensor safe". You can/will kill the oxygen sensors, instead use rubbing alcohol as a temporary lubricant.
