I recently took my jeep to o'reillys to see what the check engine light was on for. They told me I had a vacuum leak. When I got home I started looking under the hood, and found a vacuum port that didn't have a hose on it. I looked around for a dangling hose, but didn't find one. Is it possible that there should just be a cap over the hose?
On the diagram under the hood, it shows there being a vacuum port that isn't used, and I do believe that this is the port that im talking about.
