Get the codes read at the parts store. The code will tell you what needs to be fixed.

You can reset it by disconnect the positive cable of your battery than attch it back that will reset it but the best thing to do is to get the engine read to get a code you can do this for free at autozone auto parts and they will give you a paper with the possible problem.

If your light is coming on and going of by its self. This means the OBD system is detecting a problem TWICE under the same engine conditions.That's what turns on the light.When it doesn't stay on that means the condition is not constant. So when the problem is no longer present the light goes off. EXp Gas cap seal leak may come and go with air temp.

Google the trouble code. This will give you a list of things that would store the code in the O B D system and turn on the light. An engine running lean indicates that the Computer can't adjusted the time the injector stays open to maintain the proper fuel mixture. This could be caused by dirty fuel filter or a vacuum leak (letting in additional air) or a week fuel pump. (vacuum leak can also be on intake manifold)

Google code .Transmissions are also controlled by electric shift solenoids. If one of them fails it could store a code. If it's an automatic.
