Yes, a Cylinder is were the Spark Plugs Ignite the Fuel.
What that means is that either the Spark Plug, Plug Wire or Coil Pack has failed prematurely. It could also mean the the Injector or Injector Harness has failed. It might also mean a Blown Head Gasket.
Is it still under warrantee?
You could pull the Spark Plug from the #3 Cylinder and take a pic and post it here in the forum. Then we can suggest the possible cause. here is a picture to help find cylinder.......
