I saw a post a while back about some guys who were just swapping out their "ground" wires for thicker, better quality wires with nice connectors. They claim this stopped their engines from rev'ing like you describe. Maybe try that.

Well...this may be a bit obvious but check the vacuum line behind your intake manifold. It's closest to the driver's side, back of manifold, atleast on a 99 si. I was having the same idle problems and I noticed I knocked off that vacuum line, put it back on and viola...all good. Otherwise maybe a sensor like u said.
