Poor gas mileage can be a result of many many things.
First of all you need to find out what is the factory normal gas mileage for your model year Jeep SUV. It should have said on your window sticker if you bought it brand new. If you are a 2nd or 3rd owner then a Jeep dealer would have info. Google search will tell you as well, and only takes a couple minutes to find.
I did a quick Google search and for a 2003 Jeep Grand Cherokee with a (4.7L V8 engine) the average mileage is roughly 14 mpg.
Not sure what engine you have as to options, etc?
How you drive will greatly change that number up or down depending on a number of driving and driver variables.
A few being -
Engine tuned up?
Lube & oil/filter changes (every 5,000-7,500 miles? Air filter changes (every 10,000-15,000 miles)? Read your auto manual for exact recommended intervals.
How many people in the SUV on average?
Are you towing anything?
Type gas you are burning - BRAND? (See injectors below)
Area you are driving in (hills and valleys verses flat out,
Jeeps in general don't have a good track record for great mileage, and rough engine idling is always a clue that your fuel injectors are dirty. Typical on all Jeeps with port fuel injection systems! On Jeeps with dirty fuel injectors your mileage will go way down accordingly. If your not putting at least a 12 oz bottle of say Walmart brand Super Tech Fuel Injector Cleaner (~ $1 each) in your gas tank religiously every logged 1000 miles, or every 2 tank fill ups, then you are just inviting dirty fuel injectors and POOR fuel economy!
My 1993 Ford XPLR with a 4L V-6 engine (and ~ 160,000 flawless driven miles) gets roughly 22 miles per gallon on the highway with cruise control on, and about 17 around town on average. I religiously put a 12 oz bottle of the above injector cleaner in my gas tank every 1000 miles!! Of course I do all my own tune-ups, general repairs, and suspension maintenance (shocks, O2 sensors, trans oil changes, lube & oil/filter changes, code reading and clearing, etc) myself and it shows! I don't trust repair shops except for say Tires and Balancing at SEARS.
Hope that helps ease your mind about gas mileage as it relates to your Jeep there.

Check the torque on your plugs, should be around 15 - 19 lbs - consult spark plug manufacturer on the torque - if you did not torque them enough, they may have become loose. Also check coil packs - make sure all plug wires are snug.

Bad vacuum line or your OD in your transmission is not working. Inspect all your vacuum lines and TPS Throttle position sensor), also try cleaning your MAF sensor with MAF cleaner, just follow the instructions on the spray can. Cleaning the throttle body will also help on your engine's ability to be more efficient.
Start with the simple and check the vacuum lines, TPS, and make sure your tire pressure are all at 32 PSI.
Thank you for using Fixya and good luck
