Hi, i have already done a search on the forums but could not seem to find anything that resembled this problem......
my rocky a 2000 2.8 tdx has a holding back problem in low revs > , it developes a slight jerk where the power becomes a defo hold back and just seems to loose all grunt that it has on a good day, but when it comes onto boost revs at 2500 it seems to over come the general problem, this problem doesnt change if the car is hot or cold, but can some days altogether not be there! i have tried different brands of diesel and nothing seems to work any help would be appreiciated.
