Brit,

The fastest way to find a vacuum leak is with a can of "starter fluid" available from any parts place. Start up your engine and spray any suspected areas. The idea is once the mist gets sucked into the running engine through the vacuum leak, there will be an increase in RPMs. When you hear the engine "rev up", you know you have the right area. Now just turn the engine off and look in the area last sprayed before the RPM increase.

You do not want to go spraying everything at the same time. Just spray an area, and move on. The RPM increase will be immediate. After you found the area, I would stop the engine and look for any vacuum lines that are disconnected. If you are new to mechanics, it is far better to check an engine compartment with the engine off then with the fan blade revolving...

Take care,

The line you are looking for is shown in post 9 in the "issues" link but not pointed out. It is the back one on the side of the intake manifold. It supplies vacuum to operate the cruise control & the ducting for the heat/AC. The line should be hanging close to that open port on the manifold. Here is a link that shown the line above the battery & the port it attaches to. There is an arrow pointing to the port if you look closely.

Since you have cruise control that line “T”s off near the port but is not shown in the photos. The CC is on the left fender close to the vacuum port so it should be pretty easy to find the line.

Mine only came off once & is pretty tight but several have secured theirs with zip ties. If mine comes off again I will probably try that. It is kinda small for a clamp but whatever works.

The jeep might idle a little low until it readjusts to not having the vacuum leak there anymore. Just drive through it.

Ahhhhh.. Zip ties. We have an abundance of them here at work. Thanks.
Also, noticed the idle was a little low. I really appreciate the advise. Thanks again
