You have codes for 2 oxygen sensors, and 2 codes for an overly lean condition. Best to have a shop really diagnose the cause of these codes by using a live data scan while driving the vehicle. The codes are just the beginning of the process, they only point out a condition that is abnormal, not exactly which part is defective. For example, I have seen a defective Mass Air Flow Sensor cause these codes, yet there is NO code for a bad Mass Air Flow Sensor . So my point is, have a skilled person diagnose the problem that is causing these codes. here are some shops; https://repairpal.com/directory?address=45440&car_brand_names=Ford
