Sometimes if your ignition system is missing for some reason (like a
worn out distributor cap and rotor, for example), the engine will
compensate by idling really high.  When this happens, your check
engine light will intermitently turn on and off.  The engine is
programmed to idle high when cold, also, so you might also want to try
pulling codes from the computer, and/or check your temperature sensors.
