How to fix wide open throttle

I want to know how do i get my car to open up to wide open throttle when i mash on the ga spedal because sometimes it opens maybe 3/4 of the way and i have to push it again to make it open all the way. How do i Fix this?

If you have a 700R4 trans, the TV cable may be too tight. The way I set the cable is to press the pluger and push the cable back to towards the firewall. I then push the gas pedal to the floor. This will bring the TV cable out to the proper position. Remember to hit the throttle hard!
