Service engine light flashing

I have a 2005 G6 4 door sedan with 182K miles.

The service light flashes intermittently and a chime sounds. The light on the instrument panel is the one that looks like a car with a wrench.

Nothing displays on the driver information center. It does not stay on, and the vehicle runs fine.

It will do this for a few days, then stop.

Any information on this would be appreciated.

Best thing would be to plug in a code scanner and see what codes if any pop up. If that doesn't tell you anything, one of those OBDII bluetooth adapters would be handy, as they can stream all the engine parameters to your phone and you can log them so you can see whats happening when the light starts flashing.

Only time I've had my engine light flash was when one of my injectors went bad and caused a misfire.
