when you put your foot down does it chug up and seem to die, if so its your o2 sensors, either air mass or lamba?

No induction kit its nothing really serious, and it doesnt chug it just like stops for a second like stops accelerating and then goes again.

u got a decent cold air fitted rob? its just a flat spot, the torque curve on 1.2s is rather small so its more likely to get them, the best way to reduce the effects of them is a good supply of cold air and also new sensors

i had the same problem and just lived with it, now my engine managment light keeps comming on when i stop (idle) and the flat spot acurs when i pull away, sometimes the car judders and feels like it wants to stall, when i give it a few revs the light goes off and the car drives normal again. Ive been told that its a faulty Air Flow Meter (or air mass meter) they are £220 new from vaux !!
