If your fuel injector is cracked it tin can cause fuel from your fuel rails to be sent at a more rapid pace into the combustion chamber than is intended by the ECU of your engine. When your cylinder would try to burn the backlog fuel in the engine cylinders not all of that fuel would exist burnt during the process and some would be left on the spark plugs, the residual would be sent out the exhaust port.
