throttle sticks??

[DemonGT]

tonight i got on it and now if i hit the gas half way or all the way to the floor it sticks there..like if i rev it to 3 grand it will just sit there at 3..wont go any higher but if i take the tip of my toe on the back of the gas and pull the pedal out it goes down? is this my pedal or my throttle body?? and how do i fix it?
