I just bought a 2005 Pontiac Bonneville and have had several problems with it since purchasing it. The latest problems I'm having are an inaccurate fuel gage and tachometer. The fuel gauge is saying I have anywhere from a quarter of a tank to 3 quarters of a tank of gas (when I know I don't have any) and the tachometer readings are sometimes sagging well below zero. I am also currently having to live without AC/Heat (In 25-35 degree weather. Any Ideas?
