I checked light turned on I went over to Advance auto part.
They scanned the car and said it was the number one 02 senser'.
does anyone have the part number for this sensor

Tip: ALWAYS quote the code that was downloaded (not the description the parts store told you), as the code can often be caused by other things, and you may waste money replacing good items.

Did you check the flex pipe for leaks? As donbrew said a while back: "May mean an exhaust leak, a bad cat, a bad injector, a bad spark plug, a bad wire lots of other things. Don't buy parts just because the SALEPERSON who reads the codes tells you to."

You didn't mention what engine is in your vehicle - so rather than us guessing or having to confirm that the part numbers are the same between the different engines - go check out http://www.gmpartsnow.com/parts-cata...rtrain-control (note its for the 2.4l)

If you post up the trouble code number that you have we can help you more. Most times codes point you in the right direction and not to a specific part.

Without even knowing the code, my initial guess is evap solenoid (under the hood).

good guess, I'll take exhaust flex pipe leak for two hundred Alex!!
