Oxygen Sensors

[Guest]

Hi

 

Have a 350Z (2003 Fairlady) when warm/hot engine cuts out coming to a stop, works perfectly otherwise, starts and ticks over when cold and runs ok otherwise. Went into the local Nissan dealer the other week Consult diagnostic report was ECU not talking to the 4 oxygen sensors hence weak mixture. As the ECU had a performance flash download which has since been removed by the previous owner not really sure whats in there, and difficult to get hold of the original downloads from Japan for this ECU. Dealer wanted to put a new ECU on without any real proof this would sort the problem.

Looking at the ECU diagram these sensors are on a fuse, where's the fuse ? does anyone have a diagram of the fuse box ?

Any help or suggestions please.
