This happens to me periodically too. I think it could indeed be a sticky ICV, or perhaps a faulty throttle position switch.

The ICV is located on top of the inlet manifold. It has a two-pin connector. Try removing it, giving it a swish out with carb cleaner, then once it's dry squirting some silicon lube in there.

The TPS is on the throttle butterfly housing. Make sure that at idle the switch is engaging. With the engine off you should hear a little click from it when you manually open the throttle. If not, it may need adjustment.

Other things to investigate are air leaks in the pipes around the inlet manifold.
