You have to find the source of the binding. Try disconnecting the throttle cable or if automatic the cable to the trans and see if it returns fully to idle. It could just be that you need to lubricate the spool or throttle cable. A quick temporary fix would be to add a spring. Sometimes the floor mats or carpet could interfere with the pedal causing this.
