have any tricks to cheat the emissions test?

thanks brett

 

1 gallon of denatured alchohol will do the trick.

 

Do a tune up(incl oil change), get the car good and warmed up before you go so the cats are hot, run a hose directly from the air pump to the split air pipe (I've had good results with this personally).

 

I used to just run a bottle of alcohol in with about 2 gallons of gas... whomever posted 1 gallon of alcohol is crazy you will fail the test due to no reading on thier equiptment..

Thank God i live in A county that does not require testing.

 

Its denatured alchohol. Just make sure you have at least 2 gallons of gas in the tank. It works.

 

Working Cat/ Air pump. I would recommend mechanical fixes VS cheap tricks. I dont think its really good idea to put anything in your fuel system besides fuel.

As previously mentioned, a full tune up cant hurt.

You can get the ACV to pump air into the cat all the time by removing the FORWARD UPPER vac hose, and capping it.

Got emissions here too; Chattanooga. Sorry.

Good Luck.

 

What did it fail on? Last time I failed emissions, I cleaned out some of those smog equipment components and it passed after that. Sometimes those things get full of crap and need to be cleaned out, right? Also, warming up the car is excellent. Never tried the alcohol thing, but I was gonna do it if I failed again. Do you have all your cats, etc. in place? There's alot of info on this if you search. I thought all 7's had a hard time with emissions?

 

not driving a 7 will for sure do the trick!! i love reading these threads. good ole indiana lets me get away with just about anything....

i recommend cleaning all your emmissions equip and making sure your air pump is running when the test is taking place.

 

where can you get denatured alcohol?

 

yeah i live in franklin tn, near nashville, I failed by running 4x more than I should have. Where exactly is the air pump and everything. It was rebuild by mazda in 00. and it may not have been reconnected? Also I have a small exhaust leak but i doubt thats it.

 

Home Depot paint department!

 

Here is my thought on the subject. If you love your 7, you want it to run the best it can. If your 7 is running great, it will pass inspection. If your car is moddified, emissions removal, cat removal, streetport etc, then it is unlikely that a simple 'cheat' will work.

Fix your car, it will pass. You can get lots of coaching here. Do some searching. You need minimum of a tune up, a good catalytic converter and an airpump. If you do this it should pass.

Good luck!

 

does denatured alcohol trick work on regular piston engines as well?

 

gasoline containing alcohol adds oxygen to the fuel to reduce carbon monoxide and hydrocarbon emissions, doesnt matter what type of internal combustion engine.

 

how much is one bottle

 

Trying to get that post count up eh scrappy. Post crap in General automotive.

 

no really.... he says one bottle to 2 gals, how many fl.oz is one bottle

 

bboy re-animated/resurrected this thread to ask about alcohol and piston engines...nothing posted before his question is relevant. How many Oz in a bottle? Look at it.

 

Rubbing alcohol works. 16oz bottle...

 

so a half quart to two gallons of gas??

 

they do emissions in chat and franklins and murphey??? dang i live about 20 min from knoxville and i dont ahve to worry about anything

 

All of Hamilton County in general.

 

so that bottle will work for stock and not 7's with performance exhaust?? or will it?? CA smog sucks!!! oh its a 91 turbo my 90 na passes with performance exhaust however its in peak condition.

 

Bonez high flow dual cats, airpump 02 sensor tune up, aftermarket magnaflow exhaust i pass smog with flying colors. I also used SEAFOAM to clean up carbon buildup then drove for 40 mins before going to smog.

 

You're going to need to put that penguin down klrbee7. . . he knows too much.
