As above lads.

On the odd while stood still it revs on its own and then sometimes it's ok. Also when accelerating it looses power and like bogs down.

I've replaced MAFS and nothing.

Any suggestions? It's getting annoying now. :/

throttle body area mate, induction pipe split or inlet / throttle body gaskets.

just spray carb cleaner all over that area whilst it idles, if revs increase you have a leak.

clean your icv out with carb cleaner aswell.
