Eats gas runs normal - 2002 Lincoln LS

massive fuel leak or some body is stealing your gas
with that usage , it would be too rich to run
check the sump oil level as if there is injector leaks , the fuel will get to drain past the rings to the sump

it could

have you cleaned air filter, checked spark plugs. always look at the small things first, ask your garage for a blow by test to see if you have compression problems could also be head gasket any timing issue would result in a very rough idle.

it possible you have leaky injectors causing your car to run rough and burn up the gas in you tank. try disconnecting each injector one at a time while the engine is running and take note on how the engine run after disconnect each injector

chocked up air filter is the normal cause but if this is clean then it could be the auto choke isnt turning off and may need a new temperature sensor .

it sounds like the sending unit float isn't working in the tank,or gas is just running out as your filling it

the evap system is located under the truck. it will have some hoses and wires hooked to it. it should be cylindical in shape and can ussualy be blown out with compressed air. it normally never has a problem unless it eats alot of dirt

If the truck is running fine ,I would lean more towards your fuel tank it may have rusted out on you.

do you have a 5.0 v8 AWD?

I have a 1994 sls it will not go into 2nd gear. I have replaced the transmission 3 times already and i still have the same problem.
