Default Surging rpm's at idle?

Any help with what would be causing this to happen in my 2000 sc/281? The idle will surge when I come to a stop, but doesn't do it every time I come to a stop.

Could be a vacuum issue. A line and hose check might find the culprit.

Also the Idle Air Control valves go bad on these cars fairly often.

I would try cleaning the IAC and TB before replacing anything. This common, espicailly when the IAC starts getting dirty.
