Intake manifold not seated over alignment pins creating massive vacuum leak . Loosen bolts and align it better over pins.

the manifold is seated correctly, all the vacuum lines are hooked up and all the wiring is correct.

You climbed under with flashlight and looked up. 99.9 % what your describing is pin alignment underneath? ....http://www.jeepforum.com/forum/f9/in...ectly-1045108/
