Hi guys I need some help

The problem is that when I accelerate at about half throttle I can feel and hear the turbo pulsing, as if the boost in coming in & out. I done a bit of research and found possible cause could be the suction jet pump / N249 valve or the PCV system. Anyone had the same or similar.

<o:p> </o:p>

Any help would be much appreciated

Matt

i had this happening on mine to. i had noises like your describing aswell mine were more on full throttle. i had a few breather hoses split under the intake manifold, fitted new ones but nothing really changed. then a lambda fault kept popping up so when i fitted my miltek cat i popped a new probe and air flow meter on. seems to whistle away consantly now. hope this helps.
