Here's to my first post:

My Camaro has the 2.8l V6, it idles very rough after a cold or warm start. The check engine light doesn't come on until after driving for 5-10 minutes. The only code I'm getting is 45. I know the O2 sensor is fairly new, replaced within the last 6 months. What ideas do you guys have?

If there's another thread with my issue, to save everyone's time can you post the link?

Thanks guys.
