Am I missing vacuum line?

Is there a line that runs from the back left (looking at the front of the engine) of the Upper intake to something along the back of the engine?

what year/engi? Is there an exposed vacuume nipple at the places you mentioned? post pics if you can...

I have a couple pics I can post.
Maybe that will help you point out the area.

Thier are two you can see from top.
The big one left of the center and the other i the center is on the MAP.

The PCV runs over the TB and goes behind the coil packs to the O2 junct block.

PS ignore the arrows thats from another post :cwm27:

What year, model GA and what engine do you have?

On the 3400 there is a vacuum line metal fitting at one corner of the Upper Intake Manifold (UIM) pointing towards the alternator that is supposed to be plugged with a rubber fitting. It is not used but can be used as a test port to test engine vacuum with a vacuum gauge.

Sorry JC didn't see your post.

Sorry about forgetting to put the year and engine, it's a 99' GT 3.4L. I actually found the line I was looking for. It was the Brake booster line. Thanks for the help though.

Thats alright Bob, Plus I didnt mention the test port. :shakehead
