Start checking your vacuum lines, one at a time, replacing if necessary. Replace if suspect. Put a vacuum gauge in cab and try to drive with high vacuum. It tells a lot about your driving habits. Keep in mind these are only suggestions.

My problem was restricted exhaust and leaking injector. Check to see if any of your brakes are binding, 02 sensor, intake or exhaust leak.

i have an 03 jeep wrangler sahara and it was recently wrecked..they put a new rear end in it but it seems to have lost about 4 mpg.. i have 33 12.5 on it with a 3in body lift and 10in wheels..i had previously had 33 12.5 on it but with 8in wheels..and got 13 mpg.. what might have happened? rearend or somthing else?

Read up on winter gas. My mileage has dropped significantly the past couple weeks thanks to this.

A bad upstream 02 sensor can also cause a loss of power & mpg.

I also have a 97 2.5 with 30's, no lift though. I am average about 15 mpg....but I think my issue is the previous owner hadn't done a tune up. That's next month's project ( oh crap, it's next month already. Time to ask the wife for jeep money! )
