what is this and what dose it do, and could the motor run without it? (the vacumme plate with the 2 sensors)

This is your vacum control system for your Secondary Butterfly Valves and your Fuel Pressure regulator... you need that.. its essential if you still have your butterfly valves and you definately need it for your fuel pressure regulator

well i removed my secondary butterfly valves, and im pretty sure that the lil vacumme nipple thing are both broke on mine, so, what dose this mean, mine runns fine, and is faster then most of my other friends KAs

which one is broken.. both lil electronic valve thingys... ? if the one on the fuel pressure regulator is broke i believe you run rich which is why you feel a bit of power in it but your burner too much gas that the same time... also leaking a vacum out of the intake as well

I removed that completely. And if you removed the butterflies, then the only hose you need on the back of the intake manifold is one going from the fuel pressure regulator to the nipple on the back of the intake manifold for a source.
