I got the code:
P0411 Secondary Air Injection System Incorrect Flow Detected

I have no idea where to start. Okay here is what I did. I drained the oil from the oil pan and changed the oil filter. I also installed a sandwich adapter between the oil filter and engine bay for my oil temp gauge. I had to take the 3 bolts off the airbox to move the airbox forward a little bit for me to install the sandwich adapter. Put oil (5 quart) back in and moved the airbox back. Drove the car about a mile w/out the cover for the airbox. I let the car side for about an hour and went back to start it and the light came on. It's a solid CEL.

 

You might have have loosened a vacuum line while moving the air box.
This thread shows you pics of the lines to check:

thanks, there was a loose line. Hopefully it's only that.

 

not hopefully....If it is P0411 thats it.





Peace

 

You may need to wait through a few operational cycles before the CEL clears. The loose hose was the likely culprit.
