Borrowed from TPC , I havent tried this so I couldnt tell you if it works 100%

The trick I learned involves some sneaky fueling to fool the emissions testing centers. It won't damage your car and you should pass with flying colors.
What you need to purchase is a 4 L jug of methyl hydrate (sp?) from Home depot. It's in the paint section...I know this sounds a bi scarry but it worked on my old engine at the 175,000km mark and the tester said he had never seen a car pass that clean.
Ok here's what you do:
1) On the day of your test make sure your car is a close to empty as you feel getting it. I let mine get to the fuel light coming on then 20 km of driving.
2) Using a funnel (don't get the methyl hydrate on your paint) dump the entire 4 L jug into your gas tank.
3) Drive 5-10 km to ensure you are running on the methyl hydrate.
4) Go directly to the emissions place and do your test. You'll want your car to be hot (contrary to what people say it's your O2 sensor that needs to be hot not your cat. When the O2 sensor is cold the ECU just runs a pre-planned fuel mapwhich is typically rich until it warms up then the ECU adjusts fuel accordingly)
5) As soon as you've passed get yourself to a Sunoco and fill up with 94. Make sure you fill the next 2 tanks completly to the brim with 94. The methyl hydrate can be harsh on the rubber in the fuel system if you just let it sit. Thats why you need to fill up right away to dilute the methyl hydrate.
It works.
