SOURCE: high hc

you may need replace the catalytic converter, but 1st do this, clean the throttle body and idle airbypass valve, change the oil before the retest as well, get it as hot as you can before the test, hold it at a high idle prior to the test, this may squeak you by, as a 20 year smog tech these are the thing I did, if all else fails do the cat conv.

SOURCE: i did not pass smog

Well, if you didn't pass a state inspection, I can tell you how you may be able to work around it. Depending on state laws for car inspections.....I'll just give you an example: My fiance's car didn't pass inspection, but as long as she paid AT LEAST $200 to try and fix the problem, they HAVE to give her an inspection sticker for the year. We are in NC. Find out the law in your state, if you can't figure out the problem and need an inspection, spend the minimum trying to fix for now.....you'll have a year to figure it out.

SOURCE: 1991 Honda Accord LX failed emission test on smog

not enough info. Typically, CO and HC together can be the result of poor fuel control or misfire, or worn components such as O2 sensor or catalytic converter, but without more data, repair recommendations are likely to waste money and not achieve success.

Failed MEAS


wow, no context but i can read your mind?
ok SMOG failed. right?
what speed, there are 2 in uSA, 15 and 25.mph.
so there are 3 tests, which one. all are PPM in usa.
parts per million.
but is that HC , CO, or NOX? or ?

based on your numbers is HC
hydrocarbons or in barstool, its raw gasoline leaving rear of car.
unburned fuel..

572 ppm is way too high 12-19 is normal
id say the CAT is bad.
but can be , engine is bad, and burned out the cat.
that is why all savvy mechanics, check the that the engines
holds closed loop status, (EFI closed loop) at the speed yours failed.
if not in closed loop the cat will burn up (rich)
that is first.
Once that is cured. you check HC again. if out of spec
you did burn up the can , new cat time.

that is the correct way.

About the only thing you can do is take it to a qualified DEQ specialist and have them take a look at it. It might be something as simple as a hose, or not.

Failed Smog Test Close to CA-HC Limits


You can try some over the counter solutions per say. Some of the mechanics in a bottle. They sell some products This will probably be the cheapest router. If this doesn't work then you need repairs.
