Kind of hard to say without seeing all the readings and knowing the mileage, but just off hand the problem is likely the oxygen sensor and / or the catalytic converter. I would start by replacing the oxygen sensor because they are cheap and really just maintenance if the mileage is getting up there. If that doesn't bring CO down significantly then the cat is likely your problem if the engine in a good state of tune.

What does it mean when it says co


CO? That means Carbon Monoxide - it's a rather toxic and poisonous gas emitted from the exhaust system.

When they check emissions on cars CO is one of the gases they measure. If the level is too high .. your car fails the emissions test. I believe in the USA the emissions test is known as the 'smog test'?

If you have a problem with excess CO emissions on a car the cause is often an incorrect fuel/air mixture or a faulty sensor called the lambda/oxygen sensor in the exhaust system

1986 NISSAN 300ZX FAILED EMISSIONS HIGH CO


I would replace CATalitic converter, this car is old, plus a tuneup is 100% necessary , spark plugs wires, ditributor cap & rotor, plus both the air & fuel filters need replaced. change oil & filter. then you will pass emissions test. and your car will run like its suppose too. if you don't do all this , then buy a new car !

Ford failed MOT on High CO emission


High CO usualy means the O2 sensors are not reading properly. Take it to a parts store that can read codes, I know Auto Zone does in my area. If it is the O2 sensor it is an easy fix but the sensors run about $50.00 each.
