It could be a fuel injector, spark plug, or a one-time hiccup. Clear the code and wait to see if it comes back on. If yes and the code is the same, swap the injector from the cylinder indicated with the one from another cylinder. Clear the code and see what happens. If code comes back, but for the cylinder that the suspect injector now resides in, then you know injector is faulty. If code has recurred for the original cylinder, the perform the same exercise with the spark plug.
