Have you put a scan tool on it to see if it reports any trouble codes?
The data you have provided indicates the computer is unable to finish all the readiness checks; unusual given how much you have driven it. Maybe the computer is confused and just needs to be re-booted. Try pulling the 20A EFI fuse for about a half hour. This will reboot the computer and clear all of the memory. You will have to go through all of the drive cycles again. A scan tool will tell you which ones have passed and which are pending. They should all clear within 2 or 3 days of driving.

I was able to clear the code and drive about 5 miles to my local testing site and was able to pass (obviously it was "ready"). I wonder if you are having a sensor issue that's not throwing a code, but not giving enough feed back to put it into ready state. Like Bill said above, I would be looking at the bank 2 O2 sensor.

stories about synthetic oil able to clean the inside of the engine somewhat, also using a fuel injector might help not sure. I run my tank to 1/4 empty and add 2-3 bottles of injection cleaner pick your own brand.
or I guess the 02 sensor is shot?????

I would say examine the connectors and get a live OBDII monitoring device. Should be fairly quick at the dealership and may be worth the higher price you pay, but your diagnosis time may be less.

Make sure the connectors are fully engaged ,,, disconnect and reconnect and listen for the click.
