HI,I am sorry that you have not been helped yet. I just came online and saw your questionExtremely poor fuel economy can be from either spark plugs fouled out and not firing properly, faulty fuel pressure regulator, leaking fuel injectors, or fuel injectors pulsing constantly or stuck wide open.If there are any driveability issues such as misfires, hesitation, lack of power under acceleration, erratic or poor idle, you need to list them as they will help in narrowing down the issue
