Hi, I have a Aug '86 xjsc v12. It is an Australian unleaded model. I am just wondering if anyone has had experience with the oxy sensors on this model?
Do they play a critical role in keeping emissions down (i.e. like on a modern car, x300 etc) or are they just there for trimming effect?
Disconnecting them doesn't seem to have any effect at all, that's why I ask. I am also in pursuit of the best possible fuel economy ;-)
Thanks, Nick, Melbourne, Australia

Ah!! Remove the motor and insert an XJ40 3.6. THEN you will have economy :-)
Those oxy sensors are used as feedback by the computer to continually adjust the fuel injectors to get optimum air/fuel ratio into the cylinders so as to not waste fuel (rich) or burn valves (lean); I would NOT disconnect them.
hahaha good one.
thx.
Thanks, better take them seriously then and get some new ones that actually work.
Thanks, Nick.
