for the past two weeks or so whenever I drive my 4runner I have caught a whiff of gas it wasn't until about a week ago that I put it together that my car is the one putting out all the fumes. Nothing is obviously leaking from the under body, there are no drips besides the AC fluid. I would love some help on whether this is possibly a hose or connection of some sort that I could fix on my own or do I need to have a professional check it out. Please also remember that I live in Hawaii and the price of anything a mechanic does is at least 30% more than on the mainland. I have been sharing a car with my wife for the opast week, please help us get my car back.
