I drive a 94 Eagle vision but for a few weeks to a month now i notice i was using more gas each week. Like this week i filled up saturday and have only done 110 miles and used a half a tank usually i get 250 miles on half a tank. Can anybody tell me what could be the cause of this. Other then somebody possibly taking gas

you either need a tune-up and air filter or you better be looking at all your fuel lines for a leak.

Don't go chasing bad MPG unless you are sure of it. You could be spending time and money chasing ghosts. So try this experiment first:
(a) fill the tank to the max
(b) get on the HWY - late night / no traffic hour
(c) drive about 20 to 30 miles (at 55 MPH)
(d) use cruise control - very important
(e) note the EXACT MILES
(f) get off and immediately get gas
(g) note the EXACT GALLONS
Now you can calculate the MPG by
MPG = MILES (step e) / GALLONS (step g).
The reason you start out with full tank is that is the "repeatable" condition. You want to avoid traffic so you don't use the brakes on the HWY. Braking will negatively affect the MPG calculation. You use the cruise control so you and eliminate your driving habit as a factor.
Without a good MPG calculation you might be wasting your money chasing ghosts. Also you can repeat this test anytime you feel like you car is not running right. You can also try the same thing but off the cruise control to check how much your driving habit affect the MPG. etc.

Well, how long has it been since you had a tune-up? Spark plugs, Air-Filter, Oil filter, Oil, Distributor and rotor have a lot to do with your cars overall performance. Also I would keep in mind of what type of driving you've been doing ex. Highway/City that could play a factor as well. Hope this helps.

You can see if you have a leak somewhere if you have somewhere dry to park it. Let it run and see if it's dripping anywhere. Or buy a locking gas cap and see if your gas is being taken from your tank. Usely if you have a leak though you should be able to smell the gas. Are you sure that your gas needle isn't lying to you also.

A very dirty air filter has a dramatic affect on fuel consumption as has incorrect ignition timing,also check underneath the car to see if there is a fuel leak---staining on the drive---floor

To make sure your measuring the mileage properly, average 3 separate readings using this calculator

Check your published mileage specifications etc at http://www.fueleconomy.gov
