OBD Code P0411

My Lincoln has been acting funky for a few months now. Today I went to Advance Auto and had a free scan run. It came back with this code P0411. Has anyone ever had this code? The car sometimes cuts off at lights when idling and when you shift it into reverse sometimes it takes 4-5 secs, for the tranny to kick in.

This code means Secondary Air Injection System Incorrect Flow Detected. Do a Google search on obd p0411 to find out more.

Hey, if you havent figured out the problem yet, your best bet is to take the car in to the dealer and have the computer reflashed (reprogram of the pcm). That should fix slow reverse time, and will probably keep the light off. In any case, you should start with that.
