HI ya, Just got myself an nissan trail 2.2dci 2004, but having trouble when in idle, engine seems to loose power....i.e....when i am driving at start up OK, but when i come to a junction or slow down engine seems to loose power, wont go above 40mph.....if i turn engine off and on again. bingo power is resumed......it is OK on the motorway doesn't loose power only when slowing and a starting from idle.....there isn't any power there(torque)...engine will still drive but slow.......any ideas.....?
