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?
