Flashing check engine light
 

My wife just left the house and called me from 2 miles down the road. She said her check engine light started to flash, no other symtoms of a problem. I told her to pull over, shut it down then restart it and let me know if it comes back on. So she did what I said and the light did not come back on. Any ideas? bad fuel misfire? Im at a loss.

Could be anything. Without a code scanner it's anyone's guess.
