Hi I'm a newby aswell but I have been having the same problem for months.I changed the plugs,leads,cap,rotor arm and coil and it was still missing and spluttering,so I had a guy from a local land rover garage to put it on a test book and he said it could be a blocked cat,faulty coil or ECU .But after changing all of these thing it still made no differance .Now for the odd bit I cured the problem by changing the in car FUSEBOX.I don't know where you are but I have but I now have all the parts I mentioned exept the fusebox if you need them.
Hi Shaun I had a similar problem and it went on for months.I changed all the electrical parts you did and also ECU,cat,lamda,fuel pump and injectors with no change then in a fit of desperation I changed the in car fuse box on a whim as I had run out of ideas and low and behold it cured the problem.
Hope this helps Ian
try the in car fuse box.This is the last time I will reply to this post as I have tried for days but it won't reply.No fault of yours Shaun but the site won't let me reply
