    Revs dropping and cutting out

    Just started doing this, maybe its the cold but its getting annoying.

    I'll be driving down the road and come to a junction, dip the clutch and the revs drop to 400 then come back to 950rpm, some times it will cut out?

    Last time this happened to me it was a vacuum leak. Take a look at the various vacuum pipes post turbo. Also a clean up of the throttle body can cure this.

    It's probably the vac pipe under the inlet manifold.

    I had this recently, went through all of the above, turned out to be the MAF.

    Clutch switch? Not had an issue with this switch personally but i've heard the odd story about them lol

    I would of thought it was the MAF to be honest, possibly try unplugging it and see if it still does it
