Now I know your supposed to warm your diesel up as I do but here and there I will sit her warming up for only about 3 mins jump in start driving and when I sit at a steady rpm or even when I’m accelerating I feel the power go like my foot isn’t on the petal but it’s only for a split second then the power comes right back only happens when it’s cold I believe. It’s hard to tell what it is from I only just got the car 3 weeks ago and when I first got it dropped the oil and did the oil filter they didn’t have a fuel filter at the time so I left it for then had this problem thought might be the fuel filter never know so put a new one in didn’t do anything so not sure had my mate come drive it but ofc the problem didn’t happen when he was driving any help would be much appreciated it’s a 2001 hdj105 series
