I think you want to be in the 3rd Gen. section. None-the-less, I've always thought that a flashing engine light was "not good" and you should get to a service facility. Don't assume it'll go away. If you can't scan and diagnose, best to get an appt. ASAP. If it is not running smoothly, I wouldn't drive any distance at all as you can do serious damage. Good luck!

Stop at an auto parts store and have them check the engine codes for you. That will get you started.

Flashing usually means a random misfire. Mutliple misfires across all cylinders.

Building on this, server misfires will allow unburned fuel to be dumped downstream into the catalytic converter allowing a sharp temperature increase to a level where damage is likely.

Mine does the same thing. When you turn it past acc, the check engine light flashes (didn't count how many times) and then stops. It goes away whether or not i let it continue flashing or just start it up. I was curious about this too because I'm no getting any codes on my dash or my reader. And my CEL isn't on either. Maybe a bulb test like the rest of the dash lights?
