If it's slightly above the limit.. you could try putting in premium gas or an octane additive as that will lower your emissions slightly..

Before test use premium fuel. 1/2 tank. Change engine oil to lower co2 slightly and make sure engine is heated up drive in low gear for a few blocks to revv up motor for a while. Then run test again.

My 92 Honda won't pass emissions at the higher RPM


Sell the car to somebody in FL, no inspection. The state realized it was a total waste of money. Anyway, it probably is the cat, you have 3 or 4 O2 sensors, maybe more. The cat is shot, Just take out the cat, park the car in the street, Call the police in the morning and tell them somebody stole your cat. happens all the time, they go right down the road and cut out 100 cats a night, for $50 each, I don't blame them. The insurance co will buy you a new one if you have the right coverage. If not, you will have to buy a new one, because you can't use an old one. But you can sell the old one on ebay for $50. They are expensive to buy. Hope this helps.

If you are getting a Check engine Light let me know, it will make things easier to diagnose.

1994 honda accord failed its emisions test.

What will bring readings into limit


A failing oxygen (O2) -sensor will give failing emission tests. Normally you also get other symptoms:

- too high fuel consumtion
- bad acceleration, stalling problems, sputtering
- the check engine light comes on indicating that the engine control unit has recorded error codes (which will be related to readings of incorrect fuel/air ratio when read by the OBD diagnostics tool at a repair shop).

It is always a good idea to see if you can get any readings from the check engine light if present or much better by an OBD reader to be as certain as possible.

Another component that could cause failing emissions tests is the catalytic converter, giving a similar range of symptoms. To determine if this is the cause is not so easy on older cars with only one O2 sensor, it requires diagnostic skills and equipment. On newer cars with OBDII-systems it will give a recognizable fault code for the cat converter.

Then there are also the issues of the actual cause of malfunction in either or both of these components, is it due to old age and normal wear and tear or is it due to contamination from burning oil (blue tail pipe smoke) or anti-freeze (white smoke), misfiring, etc? Then the cause must be treated as well for a successful repair.

Normally these components have a very long life span and should not have to be replaced more than once or maybe twice for the sensors during the car's lifetime in an otherwise health engine.

Good luck!

1991 Honda Accord LX failed emission test on smog test. High CO and HC on 25mph


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 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.

Pass your emissions test.
