Hi, I have a Freelander td4 2006 . It's done 130,000 I bought it about 8 months ago it's in really good order but about 2 weeks ago it started to feel like it was starved of fuel every so often, just missing a beat now and again. Although the garage told me it had been serviced I wasn't sure so a fitter friend of mine changed the fuel filter and for a short time it ran ok but now it's struggling more, today I towed a trailer a couple of miles and when I put my foot down there was huge clouds of black smoke. But it still runs fine apart from hunting now and again. Any ideas . Thanks
