Question
I have Range Rover 1991 V8 3.9L and Discovery 1996 V8i 3.9L too. But I can't found O2 sensor. Where is O2 position and where is should to plug other side cable O2 sensor? what range and disco use to catalytic converter Y too? Because there is no catalytic converter in both.My car consumption 1L:5km.Is this extravagant fuel?

Answer
Hi Disyon,

send me an email and I'll reply with some technical notes to help you out with the 02 sensors.

On my '95 Disco (much like your '96), I can get over 600kms for a tank of gas (90 litres).  Your calculation gives you 450kms which is about 25% less than average.  Unless, of course, you are driving with extra large tires, loaded roof rack, rough mountain roads, etc.

I've seen Disco's with the cat's removed.  Someone cut open the pipe, did the deed then welded it closed.  

Regards,
