I'm not a mechanic, but have a 2011 Cross Country and had the same thing. Backfired thru the intake and had a ruff running, loud knocking engine. Happened twice. Each time it was a vacuum line under the fuel tank on the fuel injection intake that popped off. Ran ruff and knocked and I also thought I had a cyl problem. The second time they put a zip tie tight on the hose fitting and its held so far. Not sure if that's it, but worth a try...
