The cheapest and easiest one to check is a dirty throttle body, that's sorted my problems in the past.

Are you running a standard cat?
The post lambda won't adjust it that much to overfuel, check the throttle body and the MAF sensor first

Your post o2 sensor is there mainly to protect the CAT from damage so changing it will do nothing if you have a decat
