That diagram wasn't very specific, but thank you. I guess what I need is to know which lines hook up precisely where on the manifold.

I'm pretty certain that the vacuum lines are almost if not identical to the 2.3.

Essentially you have the lines coming from the lower intake that provide vacuum to the purge canister...which is routed through either one or two connected controllers before it hits the purge cannister on the front by the rad.

Then you have the FPR line that goes from the intake over to the FPR on the fuel rail...

There are lines that connect to the top of the intake that run over behind the engine and end up on another controller (can't remember the name) and that splits to go over to the check valve that controls the heater box air flow direction.

Do you have a vacuum leak or are you trying to track down a CEL?

Neither, actually. I had to take off the manifold to replace the EGR valve. Because of parts that didn't come in, it's been days and now I have forgotten which line goes where. If I could just find a picture of the underside of the manifold with everything hooked up I'd be fine.

Ah, OK...I see you also posted in the Urgent section...I don't have a pic of the intake connections...aside from the fact that I have a 2.5 running the 96 setup...

If you still need one and I can get to it tomorrow I will try to post one for you...
