When I replaced the O2 sensor and it didn't solve the problem I put the original back in. Learned that the hard way trouble shooting computers over the years, sometimes the new part has problems of it's own so if it didn't correct the problem I always went back to the original part.
For what it's worth after curing the P0131, P0151 codes with cleaning the MAF sensor I went about 5,000 miles and had to replace my plugs and wires due to back firing and rough running.
It's been great ever since.
