this is gonna be a tough one to tackle...BUY A FUEL CAP! lol easy as that... 99% of the time with this code, its the fuel cap. You may have dropped it, or it may have just gotten old, you can take it to any place that does emissions testing and they can test it for you. but it'd probably be cheaper to just buy a new fuel cap $10 at oriellys
