TCS not allowing throttle to open fully
I have searched on how to adjust the throttle cable on a 02' TA with TCS. I got all the slack out of the cable and even took out more slack at the gas pedal to were the throttle cable has just barely started to open the butterfly with no pressure on the gas pedal. Only at WOT the throttle body still has about 7/16" until it touches the bump stop ( this is a modified TB by POTS) The limiting factor seems to be in the TCS module where all the throttle cables go to. It seems to go all the way to the internal stop of the TCS module, and won't allow any more movement. Is the cam that is on the throttle body that the cable wraps around to large? I think that the older LS1's had a smaller cam on the throttle body. What am I missing here?

I was OK until I went to the 85mm setup and then
I ran into this; my solution was to bypass the TCS
by using non-TCS throttle and cruise cables. The
alternative would be to reduce the radius of the
throttle cam ("pulley") but there, you are kinda
stuck - only so much metal you could remove, if
you're not willing to (say) bend, slit and weld on
some tubing to make a smaller OD "track".
But be sure you don't have slack elsewhere, such
as in the non-adjustable cable from pedal to TCS.

jimmyblue- I took out all the slack at the gas pedal by shimming out the cable as it goes through the gas pedal arm. There is no slack there at all, the slightest pressure on the pedal gives throttle response. I did have to shim it over a inch, sounds about right?

throttle cable shimming
I have a 2000 ford excursion that had the same problem. There seemed to be some kind of factory shim between the gas pedal arm and the end of the cable at one point. The reason I say that is because only a small piece was left after breaking off. Your idea worked. Not only does it feel right, it's fast!
