Coil pack or injectors

  1. #1
    I have previously posted the following thread;

    My saxo has been reving by its self mainly when stopped at traffic lights also when it decides to rev when driving along normally the car will drive its self or start stuttering/jumping. I have replaced the idle speed valve and also the airbox what was broke but neither have worked what's left me stumped for what the problem is. Also recently my petrol doesn't seem to last as long, Dose anyone have any other ideas what this problem could be?

    I have now had a mechanic look at my car and he has narrowed it down to possibly being either the injectors or the coil pack.. Dose anyone know if either one of these could defiantly be causing the problem??

    I've previously looked at this car. It's like it had a misfire and runs really lumpy. Any help would be great just don't want to be throwing money at it.
