2001 bmw 740il. Car starts and engine failsafe program message comes on. Also engine seems like it's gonna pop out of hood. Very rough sounding, won't idle. What could this be?

You are experiencing a massive misfire and shouldn't run the engine in this condition. This can be ignition or fuel related but only a hands-on inspection by a technician will determine the issue.
