hey i had the same thing... the guy i got my car from..., a machanic, and his son a toyota machanic, said to tighten you gas cap... an then reset it, like take off you neg on yuor batt. you really dont have to reset it though... just check the gas cap... thats all mine was... just a thought, might help, but might not,,, but if it was after you got gas, thats most likly it, mine does it when i dont tighten it real hard.
