Eml on same codes after lambdas replaced

[Craigy69k]

As above just changed both o2 sensors after obd with genuine parts after originally putting in a generic cheapo off Amazon.. second start up and same codes are back!!

Anyone know where I should be looking next, injector check when engine cooled down?
