Anyone can pass smog very easily, I thought I actually posted this but I'll repeat for the late comers.
If you have to pass a visual, you're on your own. Thats got nothing to do with emissions.
To pass the smog test perform the following steps:
Get the gas tank almost empty, under a 1/4 of a tank
Add two gallons of denatured alcohol from Ace Hardware, Lowes or Home Depot
Proceed directly to smog station and take the test
Recieve pass certificate
Alcohol does not burn hydrocarbons, so you effectively fool the sniffer every time. I've done this on 4 vehicles now, none of which had cats. Well atleast a cat with anything inside it My 240 had over double the stock injector size controlled by a SAFC and I passed easily.
If the car has to be shutoff, you will have a little trouble starting it. It will start mind you, but not on the first crank, it will take 4-5 seconds. This is because the spark energy isn't enough to light off the alcohol mixture. Running the alcohol will not damage your motor or the sensors. Just proceed to the gas station after you pass and fill up with regular.
If that doesn't work, make a new thread or ask me on AIM or Email. I have other methods to try.
