Eh, you might be able to get it to idle right when the engine is cold or when its warm by playing with the biss but I think you would have alot of problems getting it to idle right for both because of the ecu dumping in extra fuel for the extra air it "assumes" is going to be getting past the tb plate when its idling cold. I have no experence with it personally but before dsmtalk went down I knew of several people who built an entire blockoff plate for the isc/faiv portion of the tb and they said it ran good when it was warm with a solid idle but when it was cold they had to keep thier foot on the throttle or it would stall.
IMO it would be better to "fix" the problem rather than just removing the entire system or just removing the cel bulb because that light could tell you if something more serious is possibly going out but its not my car
