Punctuation is a beautiful thing.
Im assumng this is the 3.8 Engine since you said wires.
You might also consider changing the PCV valve and the O2 sensor, the O2 sensor has a very large effect on gas mileage.
You might also check the condition of your air filter, better yet make your own intake! Im waiting on parts to make my own fender well intake right now. A better intake setup should help with gas mileage, but if youre like me you wont be able to keep your foot out of it.
I would start with an o2(oxygen) sensor though. Thats my .02

run good touring type tires (~$100 a tire) and have your tires inflated ~36psi.
