I have this problem for couple of years now I took my Crewman v6 to scan and got misfired on cylinder 1 and 5 . I have change all the coils pack and plugs then not long the check power train light came on again. So now I have change Ecu unit which is order form Australia (reconditioned) and not long light came on again. Still misfired in that area cylinder 1,5 sometime it on number 3 . What should I do next any one know pleases let me know. Wires has been checked.
