Need Vacuum Leak Help

I have a vacuum leak in my 2004 Rubicon that I cannot find at all. It is getting worse and worse. I'm assuming its a vacuum leak because nothing else matches the description. Is there a common place that I am not aware of for this to happen? It only has 62k miles on it. Note: It only does it after it warms up a little.

You can check for vacuum leak by spraying carb cleaner on different places while your engine is running. Especially intake and vacuum lines and listen for a change in engine idle. If idle changes when you spray, you've found the area of leak so you can inspect closer 'til you find the exact leak.
