is there a noticeable pause between the long and short flashes, or is the pause between the long and short flashes the same as the pause between all the short flashes. i would be willing to bet it's code 4 and 9 as was stated earlier. both are for crank positioning and cylinder positioning. if that's the case you're in limp mode and the car is trying to save itself from you reving it when it doesn't know how/when/why to fire.
