Could someone please tell me where the idle speed control valve is located?

 

Look about half way down the page 1 or control F ----> idle valve

http://www.ncttora.com/fsm/1993/engine/93throttle.pdf page EG2-239 (the procedure is uncharacteristically obtuse).

This might help to understand what the Air Valve does. http://www.ncttora.com/fsm/1993/engine/82operatio.pdf

 

It's located in/on, and/or is an integral component of, the throttle body . On the bottom side of it, roughly in between the 2 coolant lines that connect to it on each side.

More on coolant heated wax type air valves can be found on page 6 of the following .pdf

anyone out there ever seen a thermo valve fail on a 3.o throttle body: wax has oozed out of the by-pass line and is caked around the connection of bypass hose to throttle body....just wondering....time for a new throttle body i guess
