Does that have overdrive? That can account for the better mileage on highway. Do you think your trans is slipping in lower gears at all? Lots of miles there!

Alright so you have the 3.0L engine a bad o2 can effect gas mileage it tells the computer how the engine is running rich lean etc. The rear o2 sensor also tells the computer how the cat is working. If you know the o2 sensor is bad I would change it. So. What kimd of mileage are you getting?

How about miles per gallon you fill the tank up till the pump shuts off then reset the trip odometer. Then drive it down to atleast a 1/4 of a tank then fill it up till the pump shuts off. Then divide the miles driven on the trip odometer verus the gallons used.
