Ok. I am cleaning up my engine bay for a car show Friday and there is a hose that comes out of the bottom of the plenum. It is directly on the oposite side of the idle adjustment screw (screw on top looking into the engine bay, hose on bottom). While I was cleaning the dirt off of this hose I found that it was attached to.....nothing. I went threw the FI troubleshooting guide but could not find anything the shows this hose. Can anyone tell me where this hose is suppose to go to if anything?
