no, when i start, it drops where i want it to, about 7. but as soon as i hit the gas or anything else it jumps up. but then fluxuates down to where i want it, when it gets warm it stays at about 2 grand. i'm just going nuts over this thing. i'm thinkin about drivin it off a cliff and pickin up a rsx
I'm made of meat!

It has to be an intake leak. If it's fine when the car is cold and then starts misbehaving once it's warmed up, then thermal expansion is probably affecting the leak. Probably your intake manifold gasket if that's the case.
Other things that affect your idle are... TPS sensor, thermo sensor, o2 sensor, but in order to idle at 2g's it has to be getting too much air.
If you search the DIY or tech forums (I forget which) for "boost leak", you'll find a tool that can help you diagnose this. You have to make the tool. I know that DIY is for turbo setups, but if you clamp it over your throttle body and blow air pressure into the intake manifold, it will leak from whatever may be leaking. You may not easily find it without soapy water. It doesn't take much air to make your idle rise.
Another way to find it is to spray carb cleaner around the intake manifold areas that you suspect to be leaking and see if your idle changes. That's the added-fuel method.
If you just changed the TB out, make sure you put your gasket on properly. I've seen people put the gasket on backwards before, and that will definitely mess up your idle.
Plugged up AICV ports usually cause your car to stall instead of idle high.

seconded, sounds like the exact same issue I had with the AEBS intake manifold when I installed it.
It turned out not to be the manifold gasket to the head, but rather the gasket sealing the throttle body onto the manifold.
