158 Is voltage to high on lambda sensor, but it's a downstream one so it's not going to cause any running issues

171/174 indicate the engine has been running lean.

1st thing to always do...

Clear the codes and take it for a long run, then pull the codes again..

If it's truely running lean then it probably will pass emisions.
