er ive had a new front pipe and cat put on my car,and since then it ticks over at 1100 rpm,and when the engine temp gets to around 60 degrees the revs flutter between 1100 and 1400 for a few mins and then drop down to 1100.
apart from this the car drives great.
any ideas anyone?

could be something to do with the lamda sensor or idle control valve, could be other things aswell. but seeing as you've had a new cat fitted i would look at the lamda sensor being damaged or the wires come loose at the connection in the engine bay, did you get a new sensor fiited with the cat? Also i think you may have posted this in the wrong place should be series 3+4 ?? You could get a fault read done which may or may not find your problem,
