You could be running a little rich. Or, your cat for the specified bank that code is related to is toast. It could also be that the down stream O2 sensor is skewed. You would need to test the sensor or view the PID on the computer if the generic ones can do that.

Also, the permanent code is not permanent as in it will never go away. I've noticed here at Ford some DTC's that are "permanent" don't go away when you run a KOEO test unless the vehicle has gone through a drive cycle and the issue is fixed. If the issue is fixed the code doesn't show up as "permananet" no more when you run a KOEO test.
