First of all, let me start with today incident. After a nice drive home from work, I thought it would be nice to take my girlfriend out to the movies. Started my car up and it doesn't rev about 1100rpms. After idling around 600rpms, the car stalls. After three attempts, i popped the hood. Turns out the bottom loop hose that connects to the bottom of the CBV has been blown in half. Luckly, it still has enough hose to re-connect it. So thats what i did.

Started car back up with no problems.

Then i get out of the movies (5 hours later), and the car starts acting weird again. First, it takes it a long time to crank and start. (That has been going on for quite some time now) Then when it does start, it idles at 200 RPMs for about 5 seconds, struggles to hold, and then boosts its way up to 1500 RPMs. Then it idles for about 6 seconds on 750-900rpms and dies. The car has never had a steady idle. Then it starts right back up with no problems. CBV again??
I checked the hose and it was fine still.

It makes no sense. Resently i have done the following:
-cleaned the CIS
-Cleaned the throttle
-Changed the Intake Manifold gasket

Could the Cold start crank/horrible Idle problem be fuel injector related or could this pertain to the CBV? Any solutions??

I have a garrett turbo.

Thanks
