Hey guys, I have a 2000 V6. My Service Light came on like a few days ago and I checked it out at Autozone.. the code was P0411 - Secondary Air Injection Incorrect Upstream Flow Detected. The guy at Autozone had no idea what that means.. can anybody help me out please?

If my memory serves me correctly, this system adds air into the exhaust to help burn any remaining fuel in the system that hasn't already burned. Not sure where to begin looking to fix this though.

Did some digging for you, read post #23 and #26 from this link:

Fairly expensive and pointless fix I am afraid... unless anyone on here has experience with this and knows a better way to fix it.
