What does the TPS read? The blade of the throttle body could be hanging up, the iac motor could be bad, in need of tune, etc, etc, .....have you recently modified something that could have caused it?

How long has it been tuned for? If it has been tuned for quite some time and just started acting up, I wouldn't adjust anything. Just replace the IAC. All of these tables we have been talking about all adjust the IAC motor, how much to open, how much to close, how quickly to do it.
