Check that the connector to the IAC valve hasn't come off.

I'd check for any error codes first.Checking error codes VR/VS (Revised)See if anything shows up.

The IAC valve can be come clogged with carbon also.It's located on the side of the throttle body,whip it of and spray with a carby cleaner to lush it out.

Also check for a air leak on the air intake area,from the air cleaner back to the engine.Spray ny suspect areas with carby cleaner and if a leak the revs will change,as the cleaner burns.

Most times I see this it turns out to be the throttle cable that is sticking - either kinked or frayed. Sometimes a good soaking in WD40 will fix it.

I had this same problem years ago in a previous VS. I checked for error codes and I showed up a faulty 'Throttle Position Sensor' which is attached to the throttle body. Replaced that and was fixed.
