Had new inlet manifold without the swirl flaps and was told that I would not have to do anything.
I've since had it remapped and the swirl flaps deleted from the ecu. Guess what it's back
Mine being the bmr 170bhp with vacuum actuators I'm wondering if there is a vacuum solenoid or the vacuum control valve broken and that's why I'm getting the code back. I've got no lack of power what so ever.
ANY THOUGHTS PLEASE
