I decided to run the boiling test on the sensor, just to check that its ok. Its not. I´ve got the same fishy readings as last time. So still at square one.
That seems a bit odd, maybe another tack would be to test the air flow meter, as these are known to be unreliable and will upset the ECU if they go wrong and can stop the engine firing up. I still think an ECUmate would be the best way to. Investigate. Good luck.
