Unhappy 4500rpm @ idle!

I recently installed a variety of performance parts onto my 3rd. gen. For some reason when i started it just to check the basics on the power FC it shot up to 4500rpm, and stayed there, it scared the **** out of me, any one have an idea as to what it could be. I've already checked the throttle position, and the vac lines

what parts did you install? I cant think of anything that would make a car idle that high except for the throttle stuck open

take off the elbow and look at the butterflys... see where they are sitting then look around for what you touched to make them that way.... go from there.

Did you cut the wires or clip the pins to install the PFC?

the diagram should be correct...the only reason I mentioned cutting is..the cut wiring goes to the AWS, EGR, EGR switch and Split Air Solenoid...when I was troubleshooting a stock FD (no wires cut) with my PFC... after idling for a few minutes my idle jumped up to around 4,000 rpms from about 2,000 rpms...I was able to lower the idle by covering the AWS hose...
