I just bought a used 96 Ranger 2.3L 4-cyl that has 70000 miles on it. I was wondering what you guys suggest I do to tune it up. They may thing I want to do is try and get the gas mileage as good as I can possible get it.

Thanks

 

Change the plug's and wire's. The air filter should also be replaced. If you don't know the service history I would also clean the throttle body. Make certain the timing is correct.
