Thanks guys...I suspected air in the system, so that's probably what it is...

It's a slow blink, and appears immediately after the car was started from cold, so I think I can discount an engine compartment temperature issue...

Funny though, I don't know that I hear a fan in the engine compartment, however I do hear a fan running in the front of the car. The engine compartment fan comes on at a certain temperature, I would assume? I have a low-temperature thermostat in the car, and it seems to run around the 185-190 range.
