Tegger's 'Teg passes another emissions test!
With 321,000 miles on it.
That aftermarket Walker-brand cat is working much better than I expected it to. Check out the NO number especially. Results he <http://www.tegger.com/hondafaq/misc/91_integra_emissions.html> -- Tegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

The Walker has been on the car for something close to 20,000 miles, and I was honestly not expecting it to actually be functioning by the time smog came around. My primary issue with the Walker is the horribly loud ticking that it and its spring bolts make ALL THE TIME. I let the mechanic (not my usual guy) talk me into an aftermarket Walker A-pipe because he said the two would mate better than an OEM A-pipe and a Walker cat. BAD choice. The damned assembly is noisy as all get-out. I almost want to smear that stupid A-pipe with salt and chlorine in order to get it to rust out really fast so I can justify the cost of a new OEM A-pipe and bolts. -- Tegger The Unofficial Honda/Acura FAQ www.tegger.com/hondafaq/ |

Always good to see these reports. I make a mental note and then often
end up groups.google searching for some of Tegger's updates somewhere down the line. One interesting point to me: His Integra is passing smog with an 8- year-old, 146k miles O2 sensor. I had almost talked myself into replacing these every 50k miles, based on some suspicions on why my 91 Civic a few months ago could not get past smog. |

Well, now that spring is here, I'll start diagnosing my O2 sensor. Maybe even risk the cash to replace it blindly. |

For my 91 Civic and now 93 Civic, I can get the new OEM Denso oxygen sensor through Amazon for about $30. www.densoproducts.com is almost as competitive. > And it seems like they do exceed that figure by a considerable distance. > > Did you ever post your numbers when the Civic wouldn't pass? No. I had it tested several times. Mostly it failed at idle but not at high speed. The last reading before I sold my 91 Civic (to people living in a no emissions testing required county): Failed idle with HC = 460 (limit is 180) CO = 1.8 (limit is 1.2) My last theory is that I had air leaks at the throttle body gasket (you could hear them using some Tygon tubing as a stethoscope). A little Hondabond sealant fixed this. But I think the air leaks may have resulted in rich running for so long that the O2 sensor was fouled. I did some checking of the O2 sensor and it was not bouncing around 0.45 volts the way certain web sites said it should. So my next step would have been to put in a new O2 sensor. If a new sensor would not fix it, then I think I would have done a compression test and seen if the engine was just too old and worn to pass emissions. Miles per gallon was still pretty good when I sold it, so it is hard to say. At honda-tech.com I think the threads that are left unresolved most often are the smog ones for the older Hondas. |

Check out the NO number especially. > > Results he > <http://www.tegger.com/hondafaq/misc/91_integra_emissions.html> Just for comparison, my 97 Accord Wagon EX (185000 miles) just passed its UK MOT emissions test again with the following: Fast idle test: CO 0.09% (limit 0.20%) HC 13ppm (limit 200ppm) Idle test: CO 0.13% (limit 0.30%) As you can see, we don't have an NO test, or a 25mph test, or test HC at idle, so we're obviously not as fussy. As far as I know the cat and other emissions components have not been replaced ever on this car. I get about 27mpg mostly. Nonetheless, I was as happy as ever to pass emissions for another year. The only thing I failed on was the two number plate bulbs, which were working but "not bright enough"... Al Reynolds |

When you first turn on the car, it idles at about 1500-1800 rpm for a short period, and then settles to about 700rpm. The first period is the "fast idle" period. Al |
