I am having all sorts of issues chasing down a P0103 code. I have read every possible post. I have a couple of stupid questions... Be nice!

1. Is the insert that has the vacuum line, hose from breather and heating element in the hose from air box to turbo supposed to spin freely? It is in there but it can spin around. Wouldn't that let air in?

2. I did my PCV and my car only had two lower intake manifold bolts. Of course I dropped one and can't find it. Could that cause a significant vacuum leak if all of the top ones are tight and the bottom ones are not?

I did find a tear in the throttle body to IAC hose. I have ordered from Volvo $150.00!

Now my car starts fine and then dies in 20- seconds. I can force it to run with the pedal but it is misfiring. I suppose there is a big vacuum problem causing a lot of this.

I really appreciate everyone's help.
