VZ 3.6 Error codes P0047, P0203, P0003 at full throttle

[colk]

Hi all,

I have a problem where if I accelerate at full throttle and at high revs I feel a flat spot or two and then I get a check engine light appear and the car will idle rough until I clear the fault code or stop and start my car. I have a code scanner and the fault codes I am getting are below but cannot find these codes online?

P0047, P0203, P0003

Does anyone have any idea what these codes are or what they mean? I am presuming it is some kind of misfire such as ignition coil or spark plugs? Perhaps it could also be an injector?

*Update* - I think it might just be my number 3 injector voltage low? Can anyone confirm???

Thanks,
Colin

Check resistance of #3 injector. Should be 12 to 18 ohms.

Cool thanks for your help! If the codes are the same as a VX they mean the following:

P0047 Turbocharger / Supercharger Boost Control Solenoid Circuit Low (Doesn't make much sense)
P0203 Injector Circuit Malfunction Cyl 3
P0003 Fuel Volume Regulator Control Circuit Low

Does anyone know how to access the injectors in the Alloytecs?
