FYI I had posted some problems I was having with my O2 sensor going bad 2 times in 3 months. After reading over some threads, I took your advise and removed the MAF and sprayed it with some MAF cleaner. I then replaced the O2 sensor for the last time. I have noticed that the HP is much higher and even better....I am getting close to 30 mpg around town now. I found out that a dirty MAF will cause the O2 sensors to go bad or at least appear bad. Take my work for it, when you replace an O2 sensor, always clean or replace the MAF.

I do NOT agree.

Just clean / change the MAF (Mass Airflow Meter).

Only change the O2 sensors IF the output voltage is out of range.

Can save you a load of MONEY!!
