Ok so my friend asked me to look at his car. Its an 02 taurus with the vulcan. It randomly will shut off on him and not restart. Someone told him plugs and wires but i highly doubt that. It has 108k. Upon looking at it i noticed what sounded like a vacuum leak comming from the intake mani area. When you give it some gas it almost sounds like it has a intake. So my best guess is that it needs an intake gasket and possibly new manifold. What do you guys think?
