Hi I have a '93 Disco 3.9i Auto, that was originally sold as a Honda Crossroad in Japan before being imported to NZ a few years ago.
From my research it is the same as a UK spec disco of the same
age,ignoring the odd Honda Badge.
The vehicle has cats which aren't needed here in NZ, and more importantly, they have loose insides which when idling sound disturbingly like a failed rod bearing.
What I need to know is - when I remove the cats do I need to keep the O2 sensors or is it possible to change a jumper plug somewhere to tell the ECU that there are no cats and it should calculate fuelling etc based upon it's predetermined maps with data from the MAF etc. ?
Cheers
Jon
