I have searched and there is no thread like the one i am going to create ike the problem I have.

So, here is the problem. I just put a lot of time money and hard work into my current and dd 95 gs-t. Most big mods in my profile are the ones i just did within in the last month or two. I finally got my car to run and today i decided to take a cruise and log some data because my tuning abilities are little to none and my car is not running right and i was told to take a cruise log to get a better idea of things.

Well when i started the car I heard a loud hissing noise like a huge leak, so I opened the hood and the noise was coming from the intake manifold area,but I didn't feel no air coming from it. I brushed it off as maybe a new noise from all the mods done for I am new to it all. I drove about 1/8th of a mile to the local o riellys to get a alternator belt. the drive there was fine. I then drove about 300 yards to home depot and when I tried to accelerate it hesitated and felt like a boost leak. I parked and looked under the hood and what I saw was that the vacuum hose coming from the left or passenger side of the intake manifold to the BOV was clamped/sucked shut from the manifold about half way down the line. I would say about 8 inches.

Does anyone know what would cause this to happen. It might be normal but I have never noticed anything like this before and this is my third drive since I got it started with link and my new set up. the first two drives I had the car dialed in on idle and fuel. Then this drive everything was everywhere again. I will post the log if it helps.

Any and all help is much appreciated. Thanks ahead of time for the help.
 
Nope not normal for the line to be kinked. It needs to be straight. Also, air leaks are no good. If its out of boost it will pull unmetered air in causing it to run lean, and under boost it leaks metered air causing a rich condition. If its big enough, itll cause what you describe.
