I said again but it actually never got better. It just keeps getting worse. Now I am down to 200 miles to the tank when It is just about empty and I have to fill it. This is starting to piss me off. My 5.0 mustang gets this kinda mpg. `This is with a new motor (rebuilt ford) and MANY other new things. Too much to list. I used to get over 250 to a tank. What is the deal? What are some things I can check/replace to improve this? I haven't changed the O2 sensors since I have owned the car (2 years now) and they are probably the originals. I have heard mixed things about changing them. Some say changing those improves fuel economy and I have also heard that it is a myth. I dont race the car ever and almost always keep it out of the boost. I haven't checked the codes in a while so I guess I could start there. Any other ides? Thanks
