my check engine light comes on for a few minutes, then goes back off. it does this a few times while driving, while it's on the car doesn't run rough or anything (that i can notice) ... someone said it could be a bad o2 sensor, anyone have any other suggestions? its a 90 sunbird LE

its very simple and easy to do. it could be anything, so guessing doesnt work.
