2002 porsche boxster misfire: I had a problem with dirver side catalytic converter. Boxster Raodster. Changed both sensors with universal bosch, driver side. Still problem. Car started misfiring random. Changed catalytic convertor, misfire stopped for about 1 week. Misfire started again only at start up. Fuel Filter not changed yet. Air Filter not chnaged yet. All else changed. What could be the cause?
