Welcome aboard thirdgen.org.
How about a little more information. Do you live in Canada? If not, can we assume this is a factory-type computer controlled q-jet? How does the car run in general? Is the SES light coming on? Has it been well maintained? High mileage? Recent tune up? If so, what was done to tune it up? Is the car pretty much factory, or have modifications been done (like exhaust, emissions equipment, etc.)?

what kid said.
HC is usually a misfire.
NOx is usually high combustion temperature (EGR system failure.)
Has it passed in years past?
