Does anyone know what this code is and what to do about it? The engine has a very minor hesitation/sputter. It's an 02 D2 with 48K on it. I changed the plugs thinking they were getting old. They had never been replaced before. I picked up a fuel filter only to find out that there doesn't seem to be one for it. Advance Auto Parts listed it so I got one. I just returned it. Is the screen on the bottom of the tank pump the only filter? Any help would be great, Thanks
