Not holding idle

[Dr-Rotor]

First a little background. The FD was running great after a PFC tune from Ray Wilson. I got a set of underdrive pullies, so I install them. While I am doing that I do some cleaning around the engine bay with simple green. I get them installed, start the car and It doesn't hold idle. So I think it's just due to eliminating the air pump, so I reinstall stock pullies and airpump. Same thing happens. So I think maybe the simple green deteriorated a vacuum hose or somthing, they are silicone by the way. I pull the UIM and check the vacuum lines, everything appears to be in good shape. Reinstall UIM and still have problem. When I start the car it will crank, and fire, but it doesnt sound right. I can rev it to about 3k rpm but it will not go higher. Then as soon as I let off the gas it will just die. When it dies there is a sound of escaping air. The only other thing I can possibly think could be the problem would be the gasket between the UIM and LIM? Oh one more thing the wiring connector to the air pump shorted briefly during this process, but I checked all fuses and they are ok. Any advice would be greatly appreciated.
