Sorry, I just punched the code in my program and it said " Manfacturer control fuel air metering" If you hook a scanner up to the OBD II port under the drivers side dash it will tell you which 02 sensor is bad. One of the guys on the forum informed me Auto Zone will scan the car for free. You could buy one of these , thats what I did.

I bought one for 55 bucks so it worth it to look around on e-bay.
