My 4.2 efi manual gets 22/100km LPG, the old 4.2 carby auto had no trouble burning 30/100km.
Might have to take the rocks out of me Blunnies.

That is true. Most of the performance/economy gains can be reached by servicing, cleaning, upgrading the ignition system alone.

With the ECU talk does it tell you what the fault codes mean. As to what the fault is. Or do I need a list of the Nissan fault codes.
When you say the O2 sensor, do you oxygen sensor on the exhaust.
One thing I have found over the years with EFI and computers is that the engine temp must be perfect and its temperature sensors working. If not the computer will say engine cold more fuel needed. And I supose if there is to much crap around the senor in the engine the senor will not work correctly either.
