Gas pedal slack. Help!!

Are you basing non WOT on just judegement or seeing this? The trick i've used before is using large zip ties around the cable past the pedal but before the stud. This will take a good deal out of it depending on how many you use. BUT, if you go overboard than you'll put too much stress on your throttle body assembly and possibly break the spring mechanism or wedge the butterfly plate from over-extension.
