1997 Honda Prelude fuel problem?

Hi, was just wondering about the 1997 Honda Prelude. We have one that was just bought within the last 6 months, everything was good, up until a month ago. No one around here seems to know what is wrong for sure. A couple mentioned the tranny. Not sure about that. It was doing great on gas mileage, then all the sudden the maintenance required light came on along with the check engine light. It has a really strong odor of fuel also. Any help would be greatly appreciated! Merry Christmas and Happy New Year! Jolene
