Hi when the check engine light is flashing it means that it is misfiring. Could be spark plugs and or one or more coils. You can goto a autozone or bigger type autoparts store and they will scan the faults for free. The more common would be a coil. Mike

If it were misfiring, wouldn't it run rough or skip? It did niether, just the flashing light.

Hi yes it normally would. That is weird. Maybe o2 sensor fault. Or could be a problem with the instrument cluster. When there is a fault it should stay solid. When it flashes there is misfiring going on. Thats why you should have the faults checked. That will help pinpoint the area of the fault. Mike
