Hi this is my first time posting, i have a 2002 freelander td4, at the minute it tick over nicely a little smoke at the start but nothing serious, at low revs sounds ok, but after 1500 revs starts to sound like a injector misfiring machine gun going off, and a load of black smoke blowing out the exhaust, i took all 4 injectors to a diesel specialist who tested them and cleaned them, he said there were problems with the injectors at all, he said the egr could be sticking or a split in the intercooler pipe might cause the problem. I put the injectors back in and gave the egr another clean as i did this the other week but you never know it might help, put everything together and it was still the same. A few weeks ago i put some new glow plugs in as the glow plug light was not lighting up on the dash, (which it still does not) one of the plugs seems to be sticking out about a millimeter more than the others even though it seems as far as it will go would this cause the problem, any help would be more than welcome
