Sounds like a bad knock sensor or knock sensor harness. flashes while running means EZK ignition fault http://216.78.173.190/electrical_system_folder/ezkindex.htm the link has lots of EZK information Regards, KeithG "Mark the Milkman" <slycheesenopsamcom> wrote in message news:3b6ff5ae.54654308nopsam.conversent.com... > Hi folks.
