Default throttle body modification?!?!?!?!? HELP PLEASE

okay this is for everyone but i need to help!
i have a gs300 98
the throttle body works good and so does everything else nothing is wrong but i want a better response out of the throttle body!
for those who have taken apart their gs and have looked at the flange inside the throttle body and have pulled on the throttle cable. you will notice that it hardly moves! thats because of the pedal position sensor does the job of opening up the flange and allowiing the air to come in.

i need to know how to cancel it out to where it works with the cable and not a damn sensor


please help me
my names chris

I 2nd that. Noticed this too when I was cleaning throttle body. Do you also get a lag/delay response when trying to accelerate(especially after complete stop) that causes a small jerk/jump.

The Throttle Position sensor senses the position of the throttle valve and relays that info to the ecm.

The Throttle Control Motor sets vehicle speed, idle speed, cruise control, and also works with the traction control. Not a part you can easily bypass.

If the throttle control motor, or any part of the electronic throttle system is disabled the car will run using only the cable like you want but will be in limp mode.

Seems to me like you would need a new/custom engine controller to make a mod like this work.
