Ok, I finally got around to replacing all 4 sensors and I keep getting the following codes (I reset it twice and they come back within 5 miles):

P0131: Oxygen Sensor Ahead of Catalytic Converter (Cylinders 1 - 3) - Signal Wire Short Circuit to Ground or Incorrect
P0137: Oxygen Sensor After Catalytic Converter (Cylinders 1 - 3) - Signal Wire Short Circuit to Ground or Incorrect
P0151: Oxygen Sensor Ahead of Catalytic Converter (Cylinders 4 - 6) - Signal Wire Short Circuit to Ground or Incorrect
P0157: Oxygen Sensor After Catalytic Converter (Cylinders 4 - 6) - Signal Wire Short Circuit to Ground or Incorrect
P1115: Oxygen Sensor Heating 1 After Catalytic Converter - Above Upper Limit
P1119: Oxygen Sensor Heating 2 Ahead of Catalytic Converter - Below Lower Limit

I followed the instructions exactly and all the colors matched up fine. Anyone else have issues?
