    confused Z18XER juddering?

    How do guys, cuple of days ago I noticed hesitation/ juddering when accelerating but only happens some times, I know it could be a range of things but just after some advice on what it is most likely to be,no EML lights etc. I wont get a chance to have a good look(not that my limited know how will help)untill the weekend and just want her sorted in case she gets any more constipated :-)

    Would be good to get the codes read mate first off.

    Could be :-

    Plugs
    MAF sensor
    Coilpack
    Fuel filter
    Pins and needles in your right leg

    Thanks matey

    Yep have put a lot of effort into the paint work. Did more today. Will update my post on it in the next 10 mins.

    In your case with no errors I would change the fuel filter first then if needed the plugs second and go from there, well depends on what type of service you had of course.

    Yep trouty was a Delpi same as the one I replaced was second hand right enough but when the 1st one packed in I had a misfire in one of the cylinders read from the pedal test after the EML came on.

    Check the MAF (I have a spare one for the VVT) and clean the throttle bodies.
