Hi..just noticed that my car kept losing a cylinder after the car was ticking over but while driving it would kick back into four again. Pluged computer in and the code p0204 came up (injector circuit malfunction cylinder 4) just wondering is it a new coilpack i need to get or new injectors or what?
Thanks in advance

Injector #4 has a very bad reputation of getting dripped-on with water from the far-side windscreen washer-jet fittment.
This leads to corrosion of it's connector and there's been a Peugeot Info-flash about this problem.
OR it might have nothing to do with it.

Shouldn't be relevant in this case as it's a GTi and the injector's are on the front of the engine, out of harms way of the washer jets.

Ah, yes.
I forget others exist appart from the 1.4i sometimes. 
My appologies - not relevant to your model.

You could put injector cleaner in the tank and see if that does the job as it's pretty effective
With an engineers stethoscope or even a screwdriver on top of the injector you could listen to the injectors firing and compare
Swop bad injector over with a good injector position and see if the fault follows it. If it does = problem injector, if not then it points to a circuit problem.
With a multimeter you could check the injector signal and ground and resistance compare the injectors. High resistance from ECU to injector will set the P0204, as will a short circuit of course so you could check the wiring
If you have an injector tester then you can check whether the injector is operating at low rpm
If you have a scope then you can look at the injector signal trace
