air intake hose missing and something unplugged...cause of rough idle? 850

The vacuum lines are not too hard to follow in your car. There are a few on the front of the manifold, one of which goes to the SAS valve, connected to the side of the radiator.

Remove the throttle body cover and take a look at the vacuum tree. Those lines go to the PCV and air box. Sometimes, the unused vacuum port covers fall off due to age. Try to wiggle the vacuum tree, if it moves, you may need a new one with gasket.

Take a good look at the Idle control motor air lines. No cracks is good.
