O2 sensors either work or they don't & are not servicable. Replace one or both as indicated by the codes.

The MAF can be cleaned but I wouldn't worry too much about the code until you clear the ones for the O2 sensors since they could be related. Also change your air filter since that can also throw a code for the MAF.

Thanks alot. That is just the information I need. I did a search but could not find any thread about the proper O2 sensor to use. Is there 1 that is better than another?
Thanks
