Cylinder #6 misfire detected.

You might have bad sparkplug or coil-on-plug.

Major Engine Problem
Thanks for the information. My local Ford Dealer changed the Spark Plug coil on #6 however the SES light came back on after 1 day. Now they are telling me that the valve does not seat properly and I will need a major engine repair ~ $4K. I don't know what to do now. I can't believe at 68K I need a major engine repair.
