Visa versa.........

If it isn't the lambda sensors then I wonder if it is possible for the injector wires to have been swapped? From memory it wouldn't be easy but becomes possible if you unclip the lid on the cable tidy between the two banks of injectors.

All six injectors fed from common plug

Swapped out offending sensor as it's possible the routing of the wiring strained it as it exited the sensor.

Original O2 faults were persistent and intermittent 0130/0135, which the loom swap cured. Unfortunately it replaced it with the 246 misfires.

Be easy enough to swap the bank 2 plugs to rule out the -25 value.

If it was me, I would stick it up on ramps / stands with the engine running and the code reader plugged in then un plug the lambda sensors one by one just to make sure 

It is pish easy to get them the wrong way round

Maf swapped with original one to rule it out... No change, although it showed a higher idle airflow on the live data. 8.5kg/H vs 5.0 kg/h.

Should be up around 12-14, IIRC.

What are you reading the data with?

Any possibility of a large air leak into one bank? (brake servo pipe, etc)

Also, see how it runs with both Lambda sensors disconnected.

Vac pipes checked and rechecked. Plenum was removed to swap loom and everything put back in good order... Similarly, brake servo pipe removed to give clearance for 246 loom repair... Again rechecked.

Code reader is the diddy Autel one, though pedal trick gives more consistent answers. That said code reader throws up codes as pending, pedal trick confirms the codes, yet light still not on

From the common plug a little loom runs between the inlet runners to 6 individual plugs for the 6 injectors. If you don't take the plastic cable guide apart then they should never get muddled - if someone did take it apart and confudled their cylinder numbers however.......

That loom hasn't been touched

Could be an O ring hasn't been seated correctly.

What history does this car have? Is it one that has been owned by a forum member (or members)? Has it ever been known to run sweetly?

since I know car always had lambda issue
had gearbox replaced
then we replaced 2 or 3 lambda sensors
then I think Al swap plugs back to front to make sure we don't mixed them up , next cats
and now loom

Edit:
ecu was replaced too
