Hi all,

Thanks for the replies - AK Rover has correctly identified the warning light that I couldnt, thanks very much. It hasnt come back on since...a landy quirk maybe, but probably a sign that the cats are on the way out. Ive found out that can just be removed - they dont have to be replace here in 100% clean and green NZ. Truck was tuned late last year, new plug, leads, filters, runs really well.
