What MPG does a 2004 Ford Expedition get?

Looking to buy an SUV and came across an ad for a 2004 Ford Expedition XLT NBX 5.4L 4WD. The first thing I wondered was what is it's MPG? Online says it gets 14/18, but the same source says my Dakota gets 12/17 and it averages 16 mpg around town. I'm hoping there's somebody out there who has/had one and knows the exact MPG… Or what you get at least.

Will my vehicle pass emissions with a bad EGR valve?

Will my vehicle pass emissions with a bad EGR valve? - 1

Added (1). I just purchased a 2003 Ford Expedition and I noticed the service engine light on and went to have it checked out with a local mechanic. He told me the EGR is bad and it would cost $275 + labor to replace. He says that it has to do with emissions from the engine recirculating back into the injectors to recycle unused fuel. Will this affect the emissions testing?
