  • Suction control valve problem ?

    Hi all,

    KDJ125 3.0 D4D 200.000 Km with this engine problem : at 2100/2200 rpm 120 Km/h it's hunting,fluctuating in power power loss but if you accelerate it clears
    no engine light and no codes
    new fuel filter the fuel tank was clean and there was no sediment or water
    so it's scv or fuel injectors ?

    Interested to hear how this worked out.
    My son's 2.5L Navara did the same so he fitted new filter filter and a new SCV (non genuine) but then it wouldn't run properly. Surged like crazy and cut out for no reason.
    He re-fitted the old SCV and it ran as before, no cutting out but slight surging as previously.
    Wondered if the ecu needed calibrating from Nissan to suit the new SCV??
