I have a 1988 GT anytime i would go over 3,000 rpm the thottle would get stuck and the engine would rev at high rpms. I would shut the car down coast it in neutral while pumping the gas pedal then I start it and it would be fine. Soooo I changed the throttle cable and now it's worse what should I check next don't know what it could be?

Pull your throttle body and make sure the little screws that holt the throttle plate to the arm are not loose or , worse broken.... Some one on here a few months ago sucked one of those screws into the intake and down a cylinder . if they are loose or broken the throttle plate could be getting hung up.
While you have the tb off clean it and the iac valve.
If there is nothing catching the cable or linkage and all your springs are there to pull it closed and you throttle plate is intact, it would have to be at the pedal someplace

You took the nuts off first, right? Put some *** into it, a lot of times the hardware can be rusted a bit.
Yea hit the thing, I don't like rubber mallets unless they are the dead blows with sand inside them. But if you have a rawhide mallet or even a small block of wood to put on it. You can use a small ball peen and hit the block of wood.
If its really stubborn resort to the tried and true thin flat blade and tap it into the crack where they meet.
