i've got a 92 accord lx 4dr sedan and 2 months ago my gas needle floated up to full and then down to a 1/4 of a tank when i knew it had half of a tank. it does this 2 or 3 times recently. went to the salvage yard purchased a used float assembly everything was fine for about month. it has done it once again should i purchase a new one from honda or do more troubleshooting??????:banghead:
