RE: TB adjustment?
you should start a new thread on this...
look for a vacuum leak under the throttle body, you may have a base gasket that is leaking. the purpose of the IAC valve is to control how much air is leaking past the butterfly valves on the TB... if you have a small leak somewhere, the IAC cant control the air flow. Put a new TB base gasket on, torque it down per spec and see how it does. the gasket is cheep.
