when my fuel pressue reg went t!ts up, that made the co go off the scale at 10% and couldnt be adjusted on the AFM as it was to far for it to right. i would deffo look towards the AFM.

do you have a pressure gauge you could try in the fuel line going into the fuel rail, should be bout 36psi (2.5bar), when mine went wrong this was about 60psi.

also the water temp sensor on the inlet manifold tells the ECU when the engine is warm enuf to turn off cold start over fuel, if this is faulty that would also cause 7% CO

do you have any starting problem when its warm??? my was a bugger to start hot when the fuel reg was fubber.
