1988 Cherokee Vacuum line help
I've been dealing with a stumbling, stalling, problematic idling Cherokee. I noticed today that there were some vacuum lines plugged. I removed the plug in the middle line and the jeep idle fantastic. I also noticed the bottom line was plugged but did not remove the plug while the Jeep was idling so I have no idea if it will make a difference on the idle. I will attach a picture, my problem lines are the middle and bottom line of this port, if anyone knows where these lines run from here, please enlighten me.
It will not upload my picture for whatever reason. The lines I'm in question of are on a deal on the front of the intake, it has 3 ports for 3 different lines. One directly on top runs from said port to fuel pressure regulator and the two others are on the side one directly above the other. These are the two in question.

And this?
Renix Vacuum Harnesses
The vacuum harness that attaches to the front of the valve cover and includes the grommet/fitting, and is called the front harness, is Napa part number BK 715-1367
The vacuum harness that is closest to the air cleaner, EGR etc, and is called the rear harness, is Napa part number BK-715-1366.
The tube from the rear of the valve cover to the intake manifold is part number 715-1365.

Cruiser, In this diagram it's labeled "vacuum fitting" shown on the front of the intake with a vacuum line running from its top to the fuel pressure regulator, it then shows a line running from it to the air box and another running to the egr solenoid. On my jeep one fitting is right on top of the other fitting and I can't determine based off this picture which line goes to the egr and which to the air box. Any way to determine which goes where?

Looks like that fitting has 3 outlets on it.

Correct,
to the fp regulator
to the air box
to the egr solenoid
My fitting looks different than what is pictured, the fittings on the side are on the same side, one directly above the other. They ARE NOT on opposite sides of the fitting.
