What is this part?

Please see the attatched pic for the part. It is a small part that attatches to the air cleaner snorkel and has one electrical connection and two vaccum lines. I was wondering what it's function is. It is disconnected now and has been for 5 years. I was having some very bad drivability problems shortly after I bought the car in 1998. It really felt carb related. So I rebuilt the carb and it didn't help much. I then bought a new carb from Subaru. It helped some, but didn't eliminate it. I talked to a mech. at the stealership where I purchased the carb and explained what was happening. He came right out to the car and told to that disconnecting this would solve all my probs, but didn't really know what the part was. It ran 100% better after doing this.

The reason I'm asking now is that it started running like garbage again. Problem was the caps I used had cracked and created vaccum leaks. Car felt like it just wasn't getting any fuel, or running out of fuel. Runs great now with new caps. I know that the dealer wanted $170 for a new part. So can anyone tell me what it does?

No answers yet? Sorry about the size of the pic. How do you get the large pics in the post?

I have no idea. Free bump for you!

 

although I imagine its an emissions device of sorts.

hm. i have no idea what it is except that they only used it for a few months during the production run. (if it is what i think it is, pic is bad). i changed one of those on skeet's car way back when and it was hard to find one at all, let alone one without a broken nipple.

The mech. thought it was some kind of emissions part, but wasn't really sure. It passes fine without it though. All I know is that the car really runs bad when it's hooked up.
