Well done on getting the JTS error code multi-draw of lambdas and both cat efficiency ones. You've done the right thing by clearing the codes and wait see what reappears, but in my experience they likely will. On my car a couple of years ago the codes might take a few months to come back, now I'm lucky if it's more than a few days. Might actually have to do something I guess.
The pre cat JTS lambdas are different to the TS ones, as are the manifold cats themselves.
Re the airbox being open, the effect of this is dirty unfiltered air being drawn in, which can damage the MAF. But I'm pretty sure the 1172/1175 codes are lambda related - happy to be corrected if not.
