Yeah, throttle body off the inlet.

To remove the hoses, undo the hose clips and pull the hose lol, becareful though, the one under the throttle body itself can be a bit of a bitch, as it is harden plastic, I used to undo the the other end (by the Auxilary Air Valve).

You could try squirting some carb cleaner down the throttle body and into the manifold, then wipe with a rag as far as you can reach in situ to see if it helps.
