...dropped back by AZ today and asked that they check for codes again, since the CEL hasn't gone away. Still has the same 1111, 1142 and 1147 codes. However, today two new codes were observed 0327 and 0332.

If I understand correctly, the codes are:

0327 -- Knock Sensor 1 Circuit Low Input (bank 1)
0332 -- Knock Sensor 2 Circuit Low Input (bank 2)

So what does this tell me? What should be my next DIY step?

 

Maybe I should also add that I had removed the #4 ECM fuse for a few minutes, then replaced and started the cold car. It was about 40 degrees out and I did notice the car ran quite rough upon start up, then eventually smoothed out. I drove about 5 miles mostly at 55-60mph to the gym, where the car was parked for about 2 hours. Then another 2 hwy miles down to AZ, where the scan was performed.

Is it possible the new codes are do to the ECM starting from new and it being cold?
