From somewhere else:

"Air leaks after the MAF sensor, or in the EGR or PCV system Base engine "mechanical" fault affecting one or more cylinders Exhaust leaks located in front of the A/FS or HO2S location Fuel control sensor is out of calibration (i.e., ECT, IAT or MAP) Fuel delivery system supplying too little fuel during cruise or idle periods (e.g., faulty fuel pump or dirty, restricted fuel filter) Fuel injector (one or more) dirty or pressure regulator has failed HO2S is contaminated, deteriorated or it has failed Vehicle driven low on fuel or until it ran out of fuel"

I may thing that your fuel filter is dirty and need to be replaced. there is instructions in the DIY section. Also check the hoses, look for leaks. You can also run a can of seafoam with your fuel and see if that solves it.
How many miles do you have ?

i remember my car having a different code for exhaust leak, i think in the evap... who knows what. at the end, the solution for that, was to have the level of the transmission oil and engine oil in the right level. at least, that fixed the problem in those days.
