does the car idle ok as could be something to do with the control valve, also could be coil pack or ht leads possible spark plugs mate and sure somone will have a more definate answer but these are what i would start with first, also if you have been for a long run and possibly punished the car i would mayb suggest (depending on how long its had the fault) air flow meter or if you have any boost issues somehting wrong with the boost solenoid valve.

nope there is nothing else wrong with it and she idles fine just does it when it fills like lol

Any mods to the car?

just a dump valve and a vortex rear box and a uprated down pipe off the manifold had the trouble before the mods

If you hadn't had the probs before I would of possibly said the dump valve but having a decat it could also be that, mayb try changing the lambda probe mate.
