    Default Juddering and intermittent spanner light

    Just driving down A1 this afternoon and car started to judder. No warning lights so continued to see if it improved. Power under acceleration seemed poorer than usual. Anyway, came off at my junction and noticed just after going round roundabout, the spanner (car with spanner) light came on briefly then went out. Popped on once more when I was almost home but again went out.

    Any ideas? Had no problems with it up until now
    Car is 2004 1.9CDTi (150)

    Thanks

    Default

    could well be the dreaded swirl valve again....

    Code reader time to see what the codes are behind the fault...

    Vehicle : Vectra

    Trim : SRi

    Engine : 150

    Year : 05

    Mileage : 74000

    Default

    Juddering during acceleration through all the rev range points to injector number 3's wiring harness shot, (theres a mod out to replace this), pure performance from idle to 2000 rpm could be swirl valve/EGR valve.

    Default injector no. 3

    Would you know what the injector no.3 wiring modification is and what needs to be done to solve the problem? Is it a job for a VX stealer only?

    Many Thanks,
    Ched
