Default OBD2 problem P0411

Hooked up an aem v2 to my MY04 couple days back and CEL came on. Did the ol' battery unpluggin, it went away, then came back on. Auto zone guy scanned it for me (pain in the --- lookin for that plug). 2 things came up, both P0411 (Secondary Air Injection System Incorrect Flow). I'm hoping it's no big deal. Anyone with the same problem or know how to fix it? The guy took the light away, i just want reassurance that my car's 100%. Thanx

You probably have the vacuum lines reversed. Do a search for the diagram.

Fix these. Then clear the code. A friend of mine did the same thing and actually burnt his pump out by having the lines wrong. Now he needs a new pump. I would also like to add, while you have check engine codes that are emissions control related problems. Your car will be in a "limp in" mode. Less gas mileage, so I would say get it fixed !! good luck
