Hey so I know everyone and their mother has a mpg thread so why not one more! I hace a 2001 3.0 manual trans. I used to get around 16mpg in town and its steadily getting worse. It's seemed to have stopped at about 12.5 mpg. I've inspected the plugs, wires, run fuel injector cleaner, cleaned the throttle body, inspected the fuel filler neck, replaced the fuel filter and nothing. Still 12.5 mpg. I was planning on smoke testing the fuel tank to really look for cracks in the filler neck and do an efi service. But i was thinking maybe i should check the o2 sensors too? Any ideas?
