My son's Cadillac Deville had similar symptoms and I ended up tracing it down the the Idle Air Control (IAC) valve. You might check that to see if it's the problem. Here's a page that should help.

My older suburban did the exact same thing. New plugs n wires fixed it right up.

RPM Fluctuation is a common side effect of worn out spark plugs. You can try to replace these yourself or hire an Mechanic.
