Engine dropping RPM then revving

Hi

I have a 2005 Sport 5-speed. I noticed today that when I take it out of gear and coast, the RPM will drop real low just to the point before stalling and then self-rev up to 1500 RPM or so. It will do this a couple of times before idling normal.

Any thoughts on what this may be?
