its a 240... so im willing to bet it has to do with the shitty stock fuel injectors that always shit out. dont even bother replacing them with other stock ones. i went through like 3 sets. they always end up going shitty

Re: 240 gets bad gass miliage

I had the same car....could be the injectors over time could be opening up. They have rubber tips that disintegrate over time especially if fuel cleaner or gas line antifreeze gets put in the fuel system. As the tips widen they can cause rough idle, loss of power from rich fuel burn and, ultimately bad gas mileage. Also check the injector wires for tearing or splits. Hope this helps.
