Ok so ive done a search or two and everyone seems to say the same thing about lambda, map and icv etc but I have not seen anyone describe the problem with one of my symptoms.
Problem has only occurred since its been really cold, before the snow and steadily worse since.
The engine can be hot or cold, idling or in gear, under acceleration or cruising basically at any given moment without any warning.
The car has not been using excess fuel or under performing when working correctly.
But what keeps happening is a sudden loss of power and complete absence of response from the throttle for maybe 5 to 10 seconds. Once the car comes back to life the engine tone is lumpy and the exhaust is gurgley until such point as the de-cat allows it to pop, as if the engine has just dumped a chamber full of fuel into the exhaust. I will of course be cleaning all the accessible sensors first and I'll try disconnecting the lambda but can anyone shed any light to any other possible causes?

Check your plugs, if a coil pack is playing up the it should be fairly obvious when you look at them as you will not be getting a good clean combustion on that cylinder.
If you want second hand ones i have a full set off my xsara ill do you however many you want/need cheap

When was the fuel filter last changed?

Damp around the spark plugs could cause problems, won't necessarily do it from cold, more when warmed up.
