I have a '99 CSVT (duratech V-6) with 52,000 miles. Tonight, trying to come home from work, went to start the car. It would fire, but would not hold idle. Thought that maybe if I warmed it up by holding revs around 1,000 that would get me home. It would sputter, but hold idle at about 250 rpms, but if I blipped the throttle and released, engine would die. I pulled my plastic snow brush out of the trunk and started tapping things, and finally, the idle held like normal. The thing I hit that seemed to fix it is between the coil pack and the power brake reservoir, and seems to screw into the intake manifold. I suspect this is the idle control valve? Is this repairable or does it have to be replaced? Does anyone have a part #, price or procedure list? Many thanks for any assistance! 
Mine did the exact same thing a few weeks back. I let it sit for a couple hours, and it started up normally. It's happened once since then, and I sprayed some TB cleaner into the IAC (which I was advised NOT to do) and the car has run fine since. I'll eventually replace the valve, just haven't got around to it yet.
