Here in Canada your cel light means nothing...You can still pass an emissions test with your light on. Your CEL light has nothing to do with you passing an emission test. Your CEL light could be lit and your emmisions could still be well below the accepted standards. Your CEL light does not mean your emmisions are below standards...Here they check your gas cap, exhaust system for leaks, and the driven dynometer test. It always helps to take the car in when its been run and the engine warmed up, new spark plugs, fresh oil and filter, air filter, and I usually swap in a new set of wires as well. Ours here are good for 2 years.
