Yes. Fuel injectors that are worn out can "slobber" fuel into the engine creating a rich mixture. This means to much fuel, not enough air = poor fuel economy. This can also be caused by a very dirty air cleaner, bad Oxy sensor(s), bad mass air flow sensor, carboned IAC valve and a host of other things.
