The codes were P1133 and P1153. I got multiple codes indicating other problems, due to bad O2's that I purchased and installed. After the MAF was replaced, the codes continued to indicate only the 2 O2's. Per the mechanic, this was just a fluke due to a mfg error. Since I purchased from AAP, they were probably purchased from the same bad batch.
The Bosch part is purchased directly from Denso, has accurate part numbers, etc. You can purchase Aftermarket, as most Aftermarket are mfg by the same mfg's that the OEM purchases from.
The final resolution to fixing the check engine light, was replacing only the 2 O2's. I couldn't return the MAF, as I didn't have my original anymore. All other parts I installed due to codes, such as temp sensor, PCV, etc, were returned, as none were needed after the O2's were replaced with functioning O2's. The manifold was replaced too, as it was cracked...that was at my expense.
