Clogged fuel injectors?
On my former L model I had bad mileage and an uneven running motor in 
the low rpm range - below 2500 rpm,
when I had the injectors cleaned the mileage improved for about 35% and 
the engine was running smooth even when driven
a little above 1000rpm. The O2 sensor first comes to mind but if your 
emissions are ok that shouldn't be it.
