Thank you sir! I looked under the hood and the damn vacuum line wasn't even connected to the intake manifold!!! It was just hanging along the firewall collecting dirt. I connected it and fired up the Jeep, turned on the center console vents and out came a plume of dust.... LOL..
I thought it ran fine before, but that was a pretty major vacuum leak, can't wait to see how much better she responds on the drive to work tomorrow!
Thanks again for pointing me in the right direction!
