Tools needed:
Screwdrivers, Phillips and Flat
Hammer (my favorite tool)
Socket size of freeze plug
Needle Nose pliers
Vise Grips (to help break loose those stubborn screws that hold on the lower portion of the TB)
Parts:
TB Gasket
TB Elbow Gasket
This is a picture of the Idle control section of the throttle body removed. What you have to do is remove the freeze plug by means of big flat screwdriver, exposing the valve seat.
The FIAV works off the spring, when cold the spring contracts, pulling the plunger away from the seat, allowing air to go from one side of the the TB's butterfly to the manifold side, thus raising idle. When the coolant running through it warms up, it heats up the spring, expanding it, until the plunger butts up against the seat, closing up the airway, bringing your idle back down. From the factory these seats are set at a certain point where they figure that the bi-metal spring will expand enough to close the plunger against the seat, but over the course 10,000 years, they don't anymore. So you can go through the headache of finding that sweet spot again or...tada! turn it in all the way.
Here is a picture of the freeze plug removed.
Rotate the seat clockwise using needle nose pliers until it stops, thus closing the valve forever. Put the freeze plug back in via hammer and socket with a little RTV just for kicks, and viola! Free FIAV mod, or you can tackle the task of finding that sweet spot.
And some of yall thought RRE was dead, ha! we still have a few more secrets up our sleeves for these cars, only in due time we will share em.
