my little beater is giving me some problems. when i start the car, the car idles at 2k just like my rsx does while it warms up, but then it just drops, rises, drops, rises, drops to 1.2k, 2k, 1.2k, 2k. when its finished warming up it drops to 1100ish and stays there, but i dunno why it does that while it warms up. the rsx just slowly drops till its stable.

That car has both an IAC valve and fast idle thermovalve that has engine coolant running through it.

It sounds like your problem could be a combination of problems with both. You can remove the IAC valve pretty easy and clean it with carb cleaner. I'm not too sure about the thermovalve.
