Why is my 94 Camry using up way more fuel than usual ?
Only has 70,000 miles on it. Was working perfectly with amazing gas mileage. went out
of town for a week and it just sat in my driveway, it has sat much longer than that before.
Now I used up a half a tank only driving a few miles. Something has to be wrong.

Add some Lucas Fuel Injector Cleaner to gas tank. Also may not hurt to change fuel filter if have not done so in a while.
Pull a couple of plugs and see if they are all black. If so, your car is running too rich. That is usually due to a bad ECT (Engine Coolant Temp) sensor. Other causes, dirty plugs, dirty air filter, vacuum leaks, plugged EGR valve, low tire pressure, dirty throttle body, dirty fuel filter. You may just want to do a really good tune up for starters.
Forgot to mention that if your check engine light is on, you may also have a bad O2 sensor. If CEL is on, get the codes read at your local auto store. That should pin point the cause.
