SharkyMarc Posted February 12, 2010 Share Posted February 12, 2010 Good afternoon all I have a 1998 Discovery 3.9V8 Efi, running a prins LPG multipoint system, when running on petrol, it seems to use extortionate amount of petrol (circa 9mpg!) and also when its on lpg. It runs ok, a bit lumpy between 1500 and 2000 especially under load, and to try and fix this I've changed the plugs, leads and dizzy cap recently and have a CTS on order. Do these symptoms cry out for an obvious solution to anyone? I was thinking the o2 sensors were shot, but for 100 odd for a pair, its a lot to throw at it for a theory. Any help would be much much appreciated as life at single figure mpg is getting expensive!! Many thanks Marc Quote Link to comment Share on other sites More sharing options...
