Does a bad cat, mean I won't pass smog? I had mechanic tell that my 1G would not pass smog because of this and that I should replace it too.

 

[evoir]

do you not know what a cat is?

 

[brynden29]

If it is bad, then you PROBABLY will not pass. I happen to be lucky. They do not do sniff tests in Texas, yet. So I do not even have to have mine, just as long as it looks like I have one.

 

[masitaly17]

you will not pass, go buy a cat.

 

[brynden29]

^^WERD

and go ahead and get a high flow one, while you are at it

(I don't know if it will pass or not)

 

[greyforestgst]

mix in some alcohol in your tank

youll pass

 

[Tab16]

cat isn't always the culprit...

It depends which gas is too high. CO, O2 and CO2 are affected by the cat, but HCs are not. Did they give you a printout?

Hey, does adding alcohol to your gas really work? I heard your supposed to go in on a rainy day.

$75 for a high-flo magnaflow cat.. at hardcore racing...

higher octane affect results?

Hey guys, I have to go in soon too. I should pass with flying colors, but I was wondering if I used a higher octane (eg. 100) if that would affect anything? Sorry if this is a stupid question... I just got to thinking (I know... dangerous )

Cheers.

[B but I was wondering if I used a higher octane (eg. 100) if that would affect anything? . [/B]

I would suggest using what you use all the time. Probely some 92 octane right. The motor was designed to use it and unless you have a detonation problem than you should not need the higher octane.

Sorry, I don't think about that sort of stuff I'm from Kansas where it's sunny one minute, rains the next, then a tornado takes your house away.

None of these "add alcohol to gas" or other miracle home remedies will make your car pass the California emmisions test. If your car is running properly with a good O2 sensor and good Cat you should pass easily. My 92 with almost 300K was going to be a gross polluter at last test but put a new O2 sensor in it with a new cat ($90 installed) and passed by a wide margin. It's the NOx that goes off the scale when your Cat is bad.

 

[Turboholic]

It's the NOx .

Not the NOS; NAW, etc.....

Actually I don't have a cat and i passed Pennsylvania emissions testing. Of course, they didn't know that i don't have the cat in there, but hey... it just barely passed, but passing is passing, right?

It would never fly here....Smog laws are very stringent in Cali. They even use a dyno now instead of just a sniff test...fortunately AWD cars still are sniffed. But This state allows very little emmisions beyond when the vehicle is new
