It’s possible, but not recommended. You engine will misfire and can stall every now and then with out that spark plug. If the plug isn’t stuck in the socket, you should run to an auto store and purchase a new spark plug asap. If it is stuck, you’ll have to pull the engine and drill the spark plug out which is probably best left to a mechanic you trust.
