I was told to replace the O2 sensors which I did and still had the same codes come up again and again. Finally I found by research to replace or clean the MASS airflow sensor located between the air filter and throttle valve. I removed the sensor and cleaned it with a special spray cleaner. This fixed my problem completely and I had a noticeable increase in power. You can buy a can of MASS airflow sensor cleaner at most auto parts stores for about $5 bucks. I wished I would have found this out before I skinned my knuckles and cursed so much replacing all four O2 sensors. Now I clean this sensor every other time I change oil.
