Chester, No -- not yet. However I did order two new "front" (Blue and Black) 02's and probably will install them next weekend. As for the code, I had the ECM reflashed at the local Nissan dealer and that seems to have taken care of the CEL codes.
Currently the only issue I have is hard starting. Once it's running all is well, but sometimes I have to crank the starter 3-5 seconds before it starts.
