Hello,

I've replaced my computer, air filter, sending unit, fuel lines, and fuel filter. I only get 15MPG - I know I should be getting around 30. The vehicle is missing it's muffler. The tires are good, and I'm not a lead foot. I am trying to rebuild the Throttle Body now, but I really need to get this running good.

You may get close to 30MPG on a highway trip. Is the engine running good? Has the check engine light come on? Has you checked to make sure the catylatic converter isn't partially plugged?

Let me know.
