Hi guys i am a newbie so bear with me please. Recently bought a 51 plate 1.8 petrol with 53000 miles on the clock and a new engine less than a year ago. When we pull up at traffic lights or a junction etc the revs drop right off almost to a stall before settling themselves. Any ideas? On...

Had 4x4s in the past including a v8 disco, which sadly passed away a year and a half ago and is much missed. Now a proud owner of another landrover all be it a baby one, but its definitely better than the navara I had in between!! :)
