I drive a 2004 Jeep Liberty 3.7L and I was wondering what should I do to get better MPG (i dont carry anything in it but myself and tires are constantly checked) so is there any kind of exhaust system, intake system, or mod chip I should look into?

Starting from the ground up... tire pressure, oil filter, proper coolant, clean oil, fuel filter, air filter.. all will have an impact on your vehicle's performance. You neglected to state if you are doing a lot of stop and go city driving or highway driving. Your driving style will also impact your fuel economy. Keep in mind a lot of the EPA sticker ESTIMATES are done on a dyno in a lab. I drive a 2001 Ford F-150 Crew Cab with a 5.7 V-8 motor and can squeeze 17 mpg out of it on the highway.... yeah, yeah lay off on the environment issues.... while driving 80mph (speed limit is 70 where I am and I'm going slightly slower than everyone else). If anything it sounds like the Jeep you are in is UNDERPOWERED for the chasis and that might be causing higher fuel consumption as the engine has to overcome more gravity to create inertia. GMC and Chevy are NOTORIOUS for this as well... think Yukon and Tahoe.... they offer a smaller base engine and it is EXPENSIVE to upgrade to properly power those vehicles.... which are already overpriced. Hope this helps some and if you have equity in the vehicle run some figures on trading in for a new vehicle that suits your driving style. Compare annual fuel costs. Good luck.

It sounds like your Jeep is running in its normal RPM range. Fuel economy is 95% drier, 5% car. The vehicle is going to get what it is going to get. It is up to you the driver to get everything there is to get out of the vehicle - and almost nobody does. Change your driving habits and style if you want to see noticable improvements in fuel economy. Lesson one in that plan is that using the brakes converts money into heat. Every time you apply the brakes needlessly you are wasting gas by scrubbing off speed that it took fuel to achieve. So ask yourself every time you apply the brakes "how could I have done this differently to brake later or less"? When you start anticipating when you will need to slow down or stop instead of just waiting til the last second and slamming on the binders like most people you will find your foot spends less time on the gas pedal and that = better fuel economy. 20-40% better if you do it right.

Nope, maybe just a K&N filter is about as good as your gonna get for a box driving down the road.
By the way, is it 2wd, or 4wd? These matter too on mileage.

What do you consider poor mileage? The Liberty isn't an economy car.

you can try a K&N filter, but it lets in more particles of dirt along with air,, keep it in tune with new plugs and fuel filter every 30,000 miles,, plugs are cheap and I dont care what people say,, for the 10 bucks it is always worth it to me to change them out,
also air filter, and changing oil, tire pressure, all will give a mile or two more,
