What would happen if i don't put the coolant lines that goes to the FIAV on the TB? just loop the lines in the water pipe, and plug the nipples of the TB.

This is what is done to mine. Didn't see any wax when I opened mine up?
As far as I know there is a spring that expands when heated closing a port that lets a little extra air in during a cold start-up. If you remove the coolant lines do this or get a block off plate.

Correct, Sam has shown us the wax is nothing but a myth.

Correct, Sam has shown us the wax is nothing but a myth.

The "Myth" is directly traceable to the original 1G Technical Information Manual.

"The fast idle air valve is a wax actuated valve. The engine coolant circulates around the wax pellet causing the air valve to be forced out as the coolant temperature increases, thus decreasing the bypass air flow rate. The valve is closed completely when the coolant temperature is approximately 50°C (122°F) or higher."

I'm not sure anyone has pulled the whole valve assembly out of the throttle body, the wax pellet is shown as being on the other end from where the adjustable valve seat is located. The information in the TIM may be incorrect but since it's documented it's not quite a myth.
