Anybody Have An Idea Of Why....?

Alright everybody. I just replace my ISC/IAC, whatever you want to call it for 425 bux. I made it about 8 hours and then the CEL came on again. Now the car idles in a sweeping motion from about 500 - 1500 constantly. Just up and down, up and down. Any other ideas that might solve this problem. Anything simple that I may be overlooking. I am at a complete loss....Thanks...

Other than the ISC, what else have you eliminated as possible malfunctions. ie, boost leak

would boost leak affect the idle. I'm consitently running 10psi. Everything seems fine. Except for that damn idle...
