A 0.833

IDLE TEST

Well its running very rich - must be gulping fuel...
My suggestion if the readings mean nothing is to find a decent LR indy near you and get them to sort it.Most ordinary garages seem to get in a pickle with LR's.esp the Gems management system on your car.
 
an educated guess would be lambda probe, i have usually found most times that a really really high co such as 9% would be down to lambda and readings a little higher than it should be would lead to a cat.
of course this would be followed up with diagnostic checks after, but without looking at the vehicle and running some diagnostics it is just a guess and could lead to some rather expensive guess work!
 
you need the read the live data with dignostics. any indy can do this not to expensive ether.A lamba is my guess aswell. but there are two of them
also if you dont get it sorted soon your going to be looking at new cats
