Use an AC Delco, or I have Denso ones in my truck. They work good. I would stay far away from Bosch.

How do you know you have a bad one.
Codes or other?
Any code no?
What is it doing or not doing?

As with fuel pumps always use OEM GM when it comes to O2's,i just haven't found anything else that holds up as long.
