Hey all! I have had my jeep (2005 Wrangler Sport, auto) since last September, and have done minor things with it, including just a 2" body lift and 31" tires, as opposed to the stock ones I got with it. I am noticing terrible gas mileage and need some ideas to increase gas mileage that actually work. I know adding exhaust, or K/N air filters, etc...may or may NOT increase it, since the motor might decide to start running rich or lean. Anyone have any ideas and some help>?
