The car: My mods to it are flow masters, steeda cold air, short shifter and a diablo sport tuner that is taken off atm
The problem: when I floor my brakes in neutral it brings my idle down from its 700 spot were it should sit to about 200-300 (the brakes also hiss a bit when floored) it often hangs at 11 or 12 then droops to 200-300

A short video showing it happen
Thanks for any help and sorry if I miss posted in the wrong place

Well your brakes run off of pressure from your Power Steering, you are loading your pump and its probably pulling down your idle due to load. I dont think its really an issue. I imagine you are using more than stopping force, pushing ALL the way to the floor hard is just loading up the system.

I dont have mine anymore, so Im not sure where I would have the idle, maybe bump it up by 100 and see if that solves it.

Someone else will chime in here I bet and know.

I would think this is an IAC problem since it has the fiunction of holding the idle steady when the A/C or brakes put a load on the engine. I've had to replace two on my 2000gt.
