Car is flooding and running very rich and rough. Changed plugs, coils, plug wires and temp sensor. Any input would be helpful at this point.

Have you checked fuel pump pressure to make sure the regulator is working? Have you checked for a stuck injector? Have you gotten any trouble codes from the computer to indicate which cylinders are missing?
