Hi all, new owner here. I bought a 1996 2.5 diesel range rover about 4 weeks ago. I have noticed the injector/check light come on about 3 or 4 times, over the 4 weeks, with a slight loss in power for a few seconds. On thursday last week the crankshaft pulley gave up! Basically rubber had perished away. Had a new one fitted on friday and then drove home(150m on moterway)-no problem. Then saturday morning went out and the light is coming on almost every time i let of the accelarator and in turn the engine dies for a few seconds. If i drop the clutch and lift off it kicks back up until i let off again. I have searched all over the internet and have read through a few threads with the same problem but am still unsure as to what i should do. I have added half a bottle of redex which doesn't seem to have helped. My only other concern is that the cat is rattling like mad and am not sure if this could be anything to do with it??? Its also possible that the fuel may be slightly contaminated as i have filled up from a drum i had but the problem was there before just not as bad. Any help or advice would be greatly appreciated. Also if i remove the cat and weld a piece of pipe in will this be ok?
