A cylinder specific misfire indicates that either compression, appropriate fuel mixture, or spark is missing. Start with a visual inspection, looking for a vacuum leak near the cylinder. A defective PCV valve with it's inlet near the #3 cylinder could cause a lean condition. Check the compression on the target cylinder to insure that the engine is mechanically sound. Use a stethoscope to listen to the injector on the cylinder. Listen for distinctive clicks and compare to enother cylinder. I use a length of hose to the ear to check injectors. A misfire is not solely an ignition problem.
