need some help tonight!

[CV95XJ]

I just tore down the motor and finished putting it together, I got it running but its kinda rough. I pretty much just cleaned everything up and that helped, but I am concerned about one thing. As I was putting everything back together I couldn't find out what this thing was. It is coming out of the side of the fuel injection system, It is a L shape and it looks like their should be a hose or something that should fit on their, I couldn't find a hose that goes their. Im assuming it fell off or something. All Im asking for is for someone to go look and tell me what it is and where it goes too, So I can rig something up to make it work.

One thing I noticed about it was when I got it started and my brother, blocked that hole with his finger it seemed to die down and it probly would have shut off if he kept his finger on their.

THanks in advance for any help.
Im hoping to be driving it tommorrow.

What year? What motor?

Sounds like a vacuum line, but I don't recall anythign like that on the manifold except the MAP sensor elbow. You got a pic of this thing you are talking about?

[CV95XJ]

its a 97, 4.0, It comes out the side of the fuel injection system? (the big silver manifold thing) it sticks out towards the drivers side right by the brakes master cylinder. it is a 90 degree elbow that points forward. thats the best I can describe it. I already have a hose on it and Im hoping its just a breather line. so if I can get confirmation of that I'll feel better driving it tommorrow.

maybe breather hose? is there an open hole on your air filter box?

[Blaine B.]

Should be two things going to the airbox besides the main to the TB.

maybe the newer modeld are different. i have the main tube, and one breather hose... 94

well, I just assumed it was a breather and put 2 feet of hose on it and put some filter element on the end of it so dirt doesn't get in. then I mounted it up high so water doesn't get in. took her for a test drive after being down for two weeks, and she runs awesome. finally I can drive my baby again.
