MK3 7MGE Emissions Problem

Test the Oxygen sensor with a needle style volt meter. You can also check the Vf fuel trim voltage for a rich or lean condition. There is no manual adjustment as this is a fuel injected computer controlled engine. The procedure is detailed in the repair manual or online. High CO would indicate not enough Oxygen remaining to make CO2. Could be running hot also. The cat converters could be past it if euro spec cars have them. Then there are the "Pass the MOT" in a bottle concoctions out there made to lower emissions for one tank of gas. You are not far from passing. Check the timing, spark plugs, and air filter. A tune up may get you under the limit.

Cheers.
