Hi, everyone, just joined Landyzone. Had 2 series 2's and a Rangerover before. Just got a Discovery 3.9V8 '97 and having a few problems. When empty, if I put fuel in, the engine stalls 4 or 5 times afterwards when slow down then afterwards it's O.K. Also on tickover there's a high pitched noise from the engine which stops over about 800 revs. Can anyone help, please?
