I had a similar problem not with a Citroen though. It was the throttle position sensor.

did it require replacing or is it a serviceable item ??

Id change the plugs too. Serviced before you got it means it got a oil and filter before you got it.

Happens my gsxr when the iridium plugs wear out

Yes, it was only a few quid and held in place with two screws. You can test them with a meter, they are just a linear potentiometer. I don't know the measurements but someone should have them somewhere.
