On my '99 the gas gauge has been acting up. Starting about 4/5 weeks ago if I stop for a short time and get back in, the gauge is on empty and light is on. Then after driving a bit, it returns to normal. Seems to happen when there's less than 3/4's of a tank of gas. Sound like a float issue? Seems like it would be more of an electrical issue than mechanical. Anyway, any ideas or experiences that might help me?
