already searched, have emission question
My car is having trouble passing emissions, but I have new spark plugs, filters, cats, etc. What do I do?
J-rats Recipe for cheating emissions if its ABSOLUTELY necessary:
1. Turn variable resistor to full lean, or as lean as you can get and still run.
2. Trick ACV into pumping air to the cat all the time by removing the FORWARD UPPER vac hose, and capping it.
3. Run 87 octane
4. Run your tank down till your almost empty.
5. 2-3 bottles of alcohol in the tank. Drive VERY GINGERLY to the emissions station.
6. Once you pass go, DIRECTLY to a gas station and fill up with regular unleaded.
Does this work with out cats?

thanks,
for this reason i think i'm going to "give" the car to my mother in FL. so she can tag it for me and i can "borrow" it up here in MD. Florida has no inspection or emissions...

How badly are you failing?
I had my first test in MD a few months ago and failed the HC and CO parts of the test by a wide margin, about double the allowable limits. I have a mild street port NA, downpipe, and Bonez cat but I used to pass PA inspection easily. Before the test I put in new plugs and wires. At the time, I was running a Bosch "universal" O2 sensor. Somebody suggested that the NGK OEM style cuts emissions quite a bit. I got one and now I pass CO and fail HC by just .007 over the limit.
I'm thinking I might try a Random Technology stainless substrate cat since the Bonez is now five years old and probably not as effective as a new cat. Plus with the cost of the new cat, I'll have spent enough for my emissions waiver.
