Thanks for your responses...
I think I didn't make myself clear. My Cherokee has the 4.0 liter 6cyl.
I was hopeing a 4cyl Wrangler got better mileage so I would have a
good excuse to get me one. You would think it would? Maybe cause it
takes more power to run? The 4 cyl has to work harder than the 6 would?
Still doesn't seam right . What is the purpose of making a 4 cyl then?
...Oh, yeah, money....
