gas pedal stiffness???
does anyone know how we can make the gas pedal more stiff so that it'll take more effort to depress it???
i don't like how soft it feels... maybe there's a spring we could change/add to it???

Sometimes adjusting the slack (granted you have a conventional throttle cable system and not drive by wire) will help the vague feel.

The 98-00 GS400's have an actual cable attached from accelerator pedal to the throttle body assembly. Depressing the accelerator pedal with the ignition switch off only moves the Throttle Position Sensor (TPS). It does NOT open the throttle plate.
The throttle plate is operated by a throttle plate electric MOTOR, which is attached to the throttle body assembly on the side opposite the throttle cable. When the switch is turned on (as in the engine running), moving the cable end causes the TPS to move, and the TPS sends a signal to the computer. The computerthen sends a signal to the throttle plate motor to move in relationship to the distance the TPS moved when you pressed the pedal. That is why you get a lag on initially pressing the pedal. It is not bad.
That is why the throttle plate motor can control the plate when the car is in the "snow" mode. Even though the pedal is pressed nearly all the way down, the computer causes the motor to open the plate just a little bit while underway. This prevents wheelspin on wet or snowy ground.
The opposite happens when the switch is placed in the "POWER" (PWR)position. The throttle responds better and the transmission shift points are higher. This means a much more responsive car. Many drivers leave their car in this position at all times.
I really don't know if gas mileage is affected, but a lot more shifting should affect gas mileage negatively in my opinion. Maybe it just a small amount if any.
Thanks
