Hi all, as you know I have a 2006 Navara D40 just turned 100000 miles, had a new timing chain set up put in in February, august there was a funny noise and she wasn't running right , took her back and found one of the new hydraulic tensioners had failed, a brand new set up installed under warranty and had no problem since ----- UNTIL NOW - coming home tonight doing about 60/70 mph suddenly realised I was putting my foot down further and further and that nothing was happening, pumped the throttle - no response, but she was still ticking over, parked her on the side of the road, still ticking over but would not rev, tick over slowed and got very very lumpy then died, she would not restart, but if you kept turning her over it got faster and faster trying to start but not quite getting there , then she would start but would not rev and ticked over very very lumpy then died almost immediately - had to be towed and whist under tow put her in third gear and tried to bump her - she started but would not rev - was lumpy and belched out tonnes of smoke then died again whats happening ---- the only thing I've done is filled her with diesel - could this be the problem --- please help my guys thanks
