I just picked up a new to me 2000 Land Rover Disco II with 109000 on it. Ive been reading through the forums and needless to say am impressed. Body is great, paint faded and I have p0135 code so I have to replace the o2's. I did the plugs yesterday, Champion double plat's. I got an increase in power but at speeds over 30 mph I still feel it running rough. At idle hear a tick but it runs smooth. Overall I'm a Land Rover lover already and this seems to be my new hobby.
