Hello, I have a 2011 Ford Crown Victoria (police interceptor) with 240k miles. I have had it for a couple years now. No check engine light but it’s running rough any idea?

Scanning for codes and live data might be a good place to start. You could also check the usual suspects such as vacuum leaks, filters, spark plugs, and fuel pressure.
