Take a compression test of that cylinder. If it is low. it probaqbly is a burned valve, If it is ok, check for a bad injector if it is port injection. Also check for a vacuun leak. Change your spark plugs and wires.Also Check for broken Sparkplug or bad wire...I had Identical problem when I bought my 01 Nissan and it had water in the plug hole from being detailed,I sprayed penatrant oil in hole and on plug wire and problem solved within 1/2 mile.Also check for oil in the plug holes ...Most likely cause is a burnt exhaust valve BUt yes do check basics first A commoc problem is corrosion on the ignition coil especially #3 coil tower Remove the wire from the coil and make sure it's not corroded. CHeck the resistance of the wires and check the plug gap

Several things can cause a Multiple Cylinder Misfire. First and most obvious are your spark plugs and wires. If they havent been changed within the last year that you can remember its time to change them. Faulty Crankshaft sensor would also cause this to happen but is unlikely.
