    Default Loss of Power and Car Shakes

    The turbo recently blew on my vectra 150 cdti sri (Z19 DTH). All the intercooler and pipes filled up with oil, the turbo has now been replaced and all pipes fully cleaned out. My car has been running fine and then shortly after it has complete loss of power below 2500rpm. Also the whole car shakes in between 800 - 1500 rpm.

    I have ran an op com test and found no fault codes. I have also ran the injector reading test and have attatched results.

    Anyone have an idea of whats going on ?

    Injector 4 looks a bit off the +/- 3 allowance

    I did think they looked a bit wrong. What should the readings be as in the left diagram when the car is idle the reading is 2.74. Should these always be between +/-3.

    Could these be caused by the wiring, same as 3rd injector fault or is this a new injector?

    Yep I've cleaned them, just looking at the injectors and the one nearest the air box looks like its weeping diesel at the top were it plugs in.
