    Default Injector diviation on 1.9 150

    Had troubles since doing the broken cambelt and rockers.
    It starts and runs smooth and idles perfect, but is down on power and black smokes when driving.
    It has no fault codes and cleaned and checked all the usual,egr,boost and pipes etc. The only thing i found was the reading for the injectors as shown, is this normal?
    The car was fine before the belt broke and i made sure the cam and crank was marked and correct with the lines on the belt.

    Have you checked the seatings of the injectors since refitting? Start the car and spray some soapy water around the bores of the injectors. If there is any bubbling or worse (water spray) then the injectors may need to be taken out and re-seated.

    Fit new copper washers and clean the bores impeccably before re-fitting....make sure you use a decent torque wrench to tighten them up too

    Failing that try a bottle of Forte injector cleaner through it before spending big money getting re-furbed injectors

    a freind of mine had similar readings to yourself along with some smoke, we removed the injectors and left them to soak in white spirit for 24 hours we refitted them and no more smoke and if my memory serves me right i believe the readings after were about 0.50 ish
    its worth a try because as you may well know that the injectors are not cheap
