I have an '02 Sable wagon, 78k with the 3.0L Duratec. One morning last week, when accelerating onto the highway, the engine suddenly lost power and the engine light began to flash. After approximately 30 seconds, full power returned and the light stopped flashing and remained off. I did not attempt to recreate the problem because I needed to get to work. :p)
Based on research, this indicates a misfire, although I will have it scanned to confirm the code and determine the affected cylinder(s). If anyone has extensive experience with these cars, what would be the most common cause of intermittent misfire on heavy acceleration? FWIW I can perform any work that does not require engine disassembly, but I know my limits. Thanks!
