Lubricate the linkages and springs on the TB, and get an aerosol of intake cleaner, and spray that into the TB while the car is running, and try to get someone to help you do this, to keep the engine running (it will try to stall with the cleaner being shot into it nonstop several times). After you've done this, ensure the correct alignment of the TPS (the most common problem with FC TB's), and change your oil and oil filter. Also, drive the car more than you normally would for a day, and it should go away altogether. Mine sometimes used to hang up like the way you are describing about once every 4-5 months. Keeping everything clean and lubricated solved that problem every time.

Hope this helps, and good luck...
