I've Searched! Can't Find This Vac Line!!

[SHO_ROLLER_2]

Ok, I just replaced a vac line due to it being torn and making my car run like ass. So all is well in my SHO world, but it's driving me crazy that I can't find out what it is.

It's the line that goes from between the TB and IAC down to a sensor below the soil pack. THAT sensor has another line that goes somewhere else.

I was told cruise, but where's the other line going??

It's part of the emissions system. The line goes from the sensor down to a T below the radiator. IIRC one leg of the T leads to the charcoal canister in the driver side fender, and the other line goes to the tank.
