Default Anyone have a service manual or know what a weird part is?

I've got a little problem. I was installing some silicone hoses(I know, I know, but they match the Cobb CAI) and I managed to break something. There seems to be alot of cheap plastic under the hood of the 2.5RS... Anyway, it sits under the passenger side of the intake manifold. It appears to be a solenoid of some sort. It's wired into the wiring harness on the same section that the injectors are wired to. It's got 2 nipples on it. I broke one off. I got a little confused to where the hoses go. It either runs across the manifold to the top where it hooks into the manifold plenum or it may also go into the back side manifold(one is for this solenoid, the other is the cruise control, not sure) Anyway, the other hose on the soldenoid goes underneath the manifold to some metal tubing which LOOKS like the fuel lines, but there is no fuel in it. Does anyone have any idea what this does? The only thing I can think of is it's part of the vapor recovery system. Not having it hooked up doesn't seem to cause any problems except for the vacuum leak the hose makes.

huh? I've had my intake manifold off twice and you lost me.

the coolant temp sensor lives under there, but it doesn't have any vacuum lines (obviously). there's vacuum lines coming out of that part of the manifold in 2-3 places but I didn't follow the part where you were trying to describe what you broke and where it came from.

i know what he's talking about...i think it's a pulsed air system for the injectors...it creates a vacuum into the injector tip to recover and loose hydrocarbons and keep the car running cleaner.

can't really take a picture of it as it's buried... I could take a picture of the manifold and show you "it's under here" but it wouldn't be any better than "bolted to the underside of the manifold on the passenger side" All I was saying is that one of the vacuum lines runs up and over the manifold to a nipple on the driver side of the manifold plenum. The other one stays under the manifold and I can barely see that it connects to some fuel line looking tubes.

but that pulsed air system sounds plausable. That at least gives me a place to start looking...
