Pushed D-button on bracket and the black slider with teeth popped about 3/4 of an inch out of the bracket pushed it back flush toward firewall and turned it WOT. Only heard one click. Doesn't seem much tighter. Could the cable be worn? Shouldn't click more than that when you go WOT? Shifting same really maybe a little worse. Appreciate any thoughts. One other thing just switched to a larger throttle body
