hi guys any help will be good my 997 turbo has developed an annoying problem so will idle fine all day long until you rev the car then when the revs come down the car hunts and then cuts out then you can re start and the same happens isles fine until you rev it?
Move look for obvious pipes etc off and air leaks but can’t seem to see any? Anyone had this before? Thanks john

Hi Kevin thanks for the reply how would I pressure test the inlet? I had the car plugged in it come up a mass air sensor however changed them and still have problem? Regards John.
