Hi,
How is the vehicle running? The code is related to a rich fuel mixture, so I have a couple of questions. Do you have a live data scan tool? If you do, I need the following information.
1) What are the short-term fuel trims at operating temperature?
2) Check the engine coolant temperature sensor signal to see if it seems accurate.
3) Was any damage done to the exhaust system?
4) Have you verified the air/fuel sensor is within voltage specs?
5) Is this the only code that is showing up and if you delete it, does it come right back?
6) Have you inspected all plastics related to the air intake and the hoses related to the bypass control solenoid?
Let me know. If you haven't checked the bypass solenoid, put a vacuum pump on it and see if it holds a vacuum. See pic below
Take care,
Joe
