I have noticed it a few times now, but when I am riding the "check engine" light will light up, stay on for a few seconds, and then go off. It tends to happen when I am accelerating up through gears, and when I notice it, I usually let off and it goes off after a few seconds. Also, I have had it come on the same way while I am cruising between 4k and 5k rpm. I let off, and it goes away.... but I still want to know what it is about. Just over heating? Do I have a problem I should have looked at before it gets bad?
Also, it tends to happen in the first half hour or so of my ride, and I don't notice it as much when things are well warmed up.
I have plans to do an oil change soon, but if this requires some work, I will do it all at once.

Thanks for the advise!
