    I think that your truck is running way too lean, I bet the oxygen sensor codes are for lean conditions. Do you have any P0171 and P0174 codes, if so check for any vacuum leaks, and don't rule out a defective mass air flow sensor. Here is an article that I wrote that addresses lean running code/problems and how to approach diagnosis of them. http://repairpal.com/OBD-II-Code-P0171-and-P0174
