Rolling or hunting idle

1997 Expy with 5.4 has a fluctuating idle, it rolls up and down not high or low enough to be a problem, it is just a nuisance. Scan shows nothing wrong. Any ideas where to look next.

I would suspect a sticking IAC (Idle Air Control) You may be able to clean it, but usually replacement is the answer.
