Check the air filter, MAF, look for vacuum leaks and look for exhaust leaks before the o2 sensor.

shit should be warrantied?

Possible solutions include: Inspect all vacuum and PCV hoses, replace if necessary Cleanthe MAF sensor. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling Inspect fuel lines for cracks, leaks, or pinches Check the fuel pressure at the fuel rail Check the fuel injectors, they may be dirty. Use fuel injector cleaner or get them professionally cleaned/replaced. Check for an exhaust leak before the first oxygen sensor (this is unlikely to cause the problem, but it is possible)

yea thats a good one.. you need to think back and/or look for other potential RELATED issues to that code to narrow it.

Try not to use brake cleaner on the maf if you can.
