Re: 1994 Honda accord failed smog
Where are you located? If you're in Cali, things can get expensive since you pretty much have to buy an OEM Honda cat. If not in Cali, try discountcatalyticconverters.com I've used them a couple times with no problems.

Re: 1994 Honda accord failed smog
i hope you know there are many things that causes a failed smog check...not just a catalytic converter
could be something as simple as 2 dollar spark plugs vs 200+ for a catalytic converter. |
Re: 1994 Honda accord failed smog
Walker sells a CA cat. Rockauto has it listed for $168.
Sell your old cat for $90 if the honeycomb is intact. This place will pay the shipping too (no affiliation):Sell Your Cats Direct |

How was it determined that you needed a new catalyst?
Thanks to unscrupulous muffler shops making a quick buck, and aftermarket catalyst companies being cheap on the substrate coatings, you now can only purchase/use EO/CARB approved catalysts. The days of $90 bolt in catalysts are gone.

Re: 1994 Honda accord failed smog
The CO is on the high side, and the O2 seems a bit low. Combined with the high HC I'm guessing its running a tad rich. You will have high HCs if you have just improved the ignition system(installed new spark plugs) this tends to help burn off any excessive build up of carbon on the piston faces/combustion chamber.
If oil was seeping into the combustion chamber this can also cause excess HC. Same goes for if its been a while since there was an oil change. I would do an oil change if its close, slap a new air filter on, check the PCV system, and even SeaFoam the engine. The SeaFoam will help quickly clean off the excessive varnish and carbon buildup. Put the recommended amount into the gas tank, oil, and mosquito fog the neighborhood. BTW when you change spark plugs, its a good idea to also change the O2 sensor, consider it the 5th plug. Overtime it can become lazy in its response. If it becomes coated or insulated in soot it can also be slow to react. Not slow enough to cause a CEL but it can effect your mileage, power and emissions. FWIW I actually broke a O2 sensor a few years back, I knew I busted it, but the CEL never came on. On removal it rattled like a bell. Don't always expect the O2 or ECU(CEL) to tell on itself. Stick with Denso, Delco/Delphi, or NTK/NGK O2s. Other brands such as Bosch with their beer can appearance are lazy, slow to react and take forever to heat up and quickly cool down. Not good for correct O2 sensor operation.

Re: 1994 Honda accord failed smog
My 94 F22B just failed CO(%) @ 25mph. On my report, the ASM Emission Test Results for CO are: MAX @ 15mph - 0.34, and @ 25mph - 0.33 .
My CO @ 15 mph is .33, and @ 25mph is .45 I'm curious why my MAX numbers are different than Garlick's (.49/.51)? What to do? |

Since failing this test, I have changed the oil, plugs, and air filter. Don't want to retest until I cover all the bases, so your advice is most appreciated. Thanks Mike!
