4.8 intake manifold vacuum port question
My 72 has a 2007 4.8 engine. There is a port on the passenger side of the intake manifold that is open and is sucking in air. When I plug it the engine rpms go down and the engine runs fine. This must have been for some sort of vacuum sensor or whatever. It's shown in the middle of this pic. Can someone clue me in to what it's for?? Thanks
