Hi all As the tittle suggests I have this weird juddering problem that happens when I accelerate whilst moving its not the clutch. It started about a week ago after my car sat unused for a couple of weeks it was really hard to start and when it did it didn't seem right. When the fault occurs it is as if it is not firing on all the cylinders and really struggles to pick up . It doesn't happen all the time but it is really bugging me. I saw somewhere that bg44k was good so I put a can of that in but it hasn't made any difference. Could it be coil packs or something else ? Any help would be greatly appreciated as I am in no way a mechanic.
