High CO readings means it is burning too much gasoline. Emissions diagnosis and repairs are easy for a qualified repair shop. Check the emissions repair booklet that the emissions station should have given you for a reputable shop near you. Look for a shop that has a 95 or better score. That means they can fix your problem. Make sure the shop will get your car retested after they make the repair. That is your assurance they can fix the problem.
