Does anyone who owns or has owned a honda accord 1996 model or model yr close to that? if so do tou know what?

would cause the litttle maintenance required light to go on? i had an oil change about a month ago and the spark plugs were changed about a yr ago. what else could it possibly be? my only other guess would be that i need to change the fuel filter. i only want to go to a mechanic as a last resort because they will charge me an unreasonable amount just to have it looked at. any suggestions?
