Okay, well an Oxygen sensor that is stuck completely Lean will cause the ECM's fuel trim to increase fuel considerably because the ECM thinks the engine is starved for fuel, on a Volvo I have seen an O2 sensor to cause this same exact problem. The car would barely move because the O2 was stuck rich and the fuel trim was something like -100% so it was taking fuel away from the engine because it was seeing a full rich system and being fooled. Starving the car of fuel and miss firing every cylinder. You can actually check that O2 with a mutli-meter if you have one. It is really not too difficult. The O2 sensor reads only 0.1 to 0.9 volts. So not even a full volt. 0.9 volts is full rich and the lower 0.1 volts is full lean reading. You may want to change that sensor and erase the codes and go for a good long ride, but it will take a little while for the ECM to relearn the new sensor.
