Tricks to pass emissions test - Toyota Nation Forum : Toyota Car and Truck Forums

Camry mates, my '91 camry has 196, 000 miles and I would like to keep it at least until 200K. Unfortunately, the state says I can't drive it until I pass the emissions requirements for the state. I am pretty close to passing in all cases, but have failed due to increased levels of HC emissions. Does anyone know a cheap trick to get the car through? I have read that some people add ethanol to their gas to lower the hydrocarbon emission, does anyone have experience with this? Help me get the 200,000!!!

Works great! Follow the directions on the back exactly.

Know someone that does the test, pay them $10 to run them with another car and put it under your car.

That trick has never failed me.

I have heard of using denatured alcohol. I cant rememebr how much you are supposed to use though. I think it is only like one pint or quart for ten gallons or something like that.

This trick worked for a 1984 Audi 100 turbo that my brother had, although I am unsure what made the car fail in the first place.

The emissions tech told him to go haul

on the interstate, and then immediately return to the emissions station. Passed with no problem, and actually somewhat clean.

I found a place in CA to register my car with no Emissions: Forestville.

Thanks everyone for the advice. I have recently moved to the area, so unfortunately I have not made friends up with a mechanic yet as nothing ever goes wrong with my car! I am going to try replacing the air filter and plugs and use a fuel additive (ethanol). I'll let you all know how it turns out. I am actually very close to passing. I was actually doing some research and it appears that cars pre-95 or so were designed for the older and more generous emissions requirements, what I tested at was actually right in line for how the car was designed. I would live to be able to hold out to buy the new model! It looks fantastic.

On the current tank of gas add some Techron or similar injector cleaner.Then use some throttle-body cleaning spray, then change the plugs and oil. When the gas tank is near empty put in 1/4 tank of premium gas and a bottle of gas line anti-freeze (alcohol). Before the test, be sure the motors is at operating temp. Give it a good run before the test.

wow... doesn't look easy... how will my older toyota do? the emissions are hard to read... my friend passed his old ford with info and a tip that he got from www.smogsecret.com and I wonder if the secret additive they talked about was the stuff mentioned earlier cause I'm pretty sure he measured up something and put it in

A buddy of mine who has been an auto mechanic for thirty years has always advised people worried about passing to simply take your car out onto a nearby freeway and run it for about 15 minutes at high-speed. Obviously you have to use your better judgment about how fast based on safety and getting a ticket, but here in California 80 MPH is the flow of traffic. Anyway, he suggests that kind of speed for at least 15 minutes then drive straight to your emission check appointment with all your points very hot, etc., and you'll pass. Don't have any proof that it works, but that's what one mechanic recommended.

A friend knows people. It's cheaper and I tag along with some of the SR-swapped 240sx guys!

$20/each for sure pass

You can run the motor harder/hotter at legal speeds by disengaging overdrive on the highway, using 1st/2nd in town, etc.

2000 sienna failed (no.) part of test. added guaranteed to pass. ran vehicle for 500 kilometres . took it back well warmed up for 20 minutes. tested immediately and it passed with a 44 reading instead of 1344.

maybe where you are you can get away with it... but in most states they have state inspector "straw customers" to check up on the smog test shops. The smog shops know this and they also know there's no way to tell who's who. So 95% are not going to deviate one millimeter from the state law, because the fine from EPA or whoever can put them out of business. So i wouldn't count on this trick unless you know someone personally who owns a smog shop.
