At the risk of saving you some $$$$$...take it to the dealership. What you have is the dreaded 3.8l cracked exhaust manifold(s). It is covered under the emissions warranty up to 80,000 miles. The 3.8l (aka minivan engine) was never designed to take the high RPMs that are produced by the Jeep so the exhaust finds the weakest point to put stress on and that is the manifolds. It is cheaper for Chyrsler to replace the broken ones than to do design better ones on an obsolete platform, do a recall, and install the new ones because most people don't realize that is the problem. They think they need to use better gas!
Mine are both cracked and I have the same symptoms you are describing. I am just too lazy to get it over to the dealership!

I took a video that I want to upload, is there a way of putting it up easily via iPhone?
The more I listen to it, I do believe it's an exhaust leak at the manifold. But if still like to upload to see what everyone else thinks.

Right on. Thanks everyone, I bought it about 4 months ago with 65k miles. Now it's got about 72k. Probably not covered by factory warranty, but I did purchase a warranty when I bought the jeep, so maybe that will cover it
