Well, the cruise control I've always wanted has now become an unfortunate reality.

As I press down on the pedal - normal operation. When I let off - it'll come back about 1/3 of the way but I have to reach behind it with my toe to pluck it back. I have already removed the pedal.

Removed the air filter/cleaner and checked for obstructions, and don't see any. One of the springs looks to be a little worn, and where it connects back to the intake, the small plate is loose. I manually held the plate back a little bit and had my wife hit the throttle. Situation improves, but not by much. This is a relatively new problem - the car sat garaged for about 2-3 months (through the worst of winter) and gets driven about 4-5 times per month on a regular basis.
