'88 GT throttle sticking problem

Has anyone had this problem before? I have an '88 GT with stock 5.0 in it and I seem to have a throttle problem. When it had the stock throttle body on it I don't recall it ever doing this. I put a Proffesional Products 70mm throttle body and spacer on it not to long ago. When the engine is not running you can push the gas pedal down and it goes down nice and smooth. When the engine is warm and running it is very hard to push the gas pedal down at first. It is like it is frozen when you first try to push it down and once it breaks free it goes right to the floor smooth but when you let it up it sticks again. This causes me to do burnouts on the street that I really DONT mean to do. Seriously. As soon as you turn the engine off this problem goes away completely. The pedal becomes nice and free until you start the engine again. PLEASE HELP I NEED TO DRIVE THIS CAR ON THE STREET AND DONT WANT TO GET STOPPED FOR UNNECESSARY BURNOUTS!
