Can anyone point me in the direction of what hoses to inspect please.
Currently have the TB removed, lots of carbon, but no actual chunks,
butterfly valve cannot fully close though, should it close to the mating
surfaces ?
Thanks again
Stuart

Apologies for replying to myself, but since it was good news, I thought I
would share it.
Just to let everyone know the cleaning the throttle body internals did the
trick.
I would like to say a HUGE BIG THANKS to everyone especially Alec for
pointing me in the right direction.
Thanks a lot.

Great stuff - now go and tell the skanky garage & either ask for your money
back on the MAF or at least get the old sensor back from them. Given that
you are also 700 quid better off than you might have been I guess the beers
are on you (!)
