    Vehicle : Vectra

    Trim : SRi

    Engine : 150

    Year : 05

    Mileage : 74000

    That bar is controlled by a motor on number 3 cylinder swirl valve to control the others. The idea behind it is that at low revs it closes off or opens (cant remember which way round it is now) one of the two air inlet valves thus making it more effiencient at low speed. As rpm/speed rises this opens or closes (again cant remember which way) to increase better running..

    Thread mentioned above will explain how to fix it. But these valves can coke up and cause them to stick open/shut

    Whilst mine was knackered i did notice more smoke than usual but after a complete inlet manifold change of this (due to revised design of components) and a cleanup on the EGR valve all smoke was gone.

    Symptons would be bad idle possibly and/or poor performance below 2000rpm.. take that only as a guide line. I've got one i'm looking at tomorrow with the bar off but feels quite fine to drive.
