The knock control issue could be as simple as needing better gas. Maybe try a different (busy) station.The fact it drops down to .49 eventually is good. As far as the code, this is what I found. It's a cold start idle issue:
"The P050D code can result from a number of different problems. For example, if the Engine Coolant Temperature (ECT) sensor is malfunctioning, it may result in this problem due to issues with the vehicle in question detecting what is and is not a cold start. Other malfunctioning engine pieces, such as fuel injectors, bad spark plugs, plug boots, and ignition coils, can also result in this problem, as can problems with the wiring and connectors attached to these areas. A vacuum leak or intake system leak can also cause insufficient fuel delivery or insufficient fuel pressure, leading to a problem with the air/fuel ratio."
If you can, go ahead and post up a datalog (in a .zip file for posting). Start the datalog at start up and do about 25 minutes of driving with a pull mixed in, if possible.
How many total miles do you have on the car?
