3S-GE throttle body theory
Does anybody knows: how the 3S-GE throttle body exactly works?!
The warm water runs through the ISC(?) system. When has effect this? When it is warmed up or when it is cold? What does the cold and the warm water EXACTLY?
There are 3 ways for the air:
1. Butterfly (controlled by gas pedal)
2. ISC electronic valve (controlled by ECU & with water lines?)
3. Idle speed screw (adjustable manually)
On my throttle body (from a 182 Celica) there are no other ports. There are no evap input, no EGR input.
