Engine running rough

I have a 98 Expedition 54L. The engine is running very rough (heavy vibration), but no pinging or knocking. I can also smell exhaust inside the cabin as well. Check engine light is on. Any ideas what might be causing it?

run an engine scan first to see what sensor or sensors have failed.
