Re: High emissions. How to cure?
A rich mixture will cause HC and CO to be high. Is the SES light on? A misfire or leaking "nut kit" or fuel pressure regulator would be the first thing to check. How does the engine run? With those numbers it probably runs fairly well. Check fuel pressure and check for excessive leakdown. Cheap and easy to test it. Lambda, (Oxygen sensor) voltage is high also, indicating a rich condition. Post your results.
