I took the cat off 2 years ago. I think I'll hook up a new sensor like you say. |

I would if it were my car, at least I would try it, unless the computer system is so screwed up that it would be cost prohibitive. The car would be much more efficient with the same power. Your car should have come with a cat. unless someone removed it. |

Herbert,
I don't have a cat on the car. Should I still hook up a new sensor? |

Hi Dr. You just got 2 of the best opinions on this chat line. Herb and Peter. I would take it to the bank. Good luck with your check up. |

If the O2 sensor has been disconnected for a long time then it is probably not going to work when reconnected due to carbon coating from being too rich. The catalytic converters require a 14.7 to1 air fuel ratio to operate at their peak efficiency and that is exactly what the O2 sensor delivers if all is operating properly. If this were my car I would first eliminate the converters for the future dependability of the engine, but get the computer system working again because it is so efficient. Almost all O2 sensors work the same, so if it has the same number of wires which probably is one, any will work. I use AC Delco in most all applications as they make a good product and is less expensive than most. Just go to any GM dealership and ask for a one wire sensor and it will be around $50.00. The wire end where it hooks up will be different but just clip it off and use the one off the old sensor. After you replace the sensor you will need a voltmeter capable of reading one volt because that is the parameter you will be working with. After warming the car for about 5 minutes you should be reading a varying voltage from the sensor from zero to about .9 volts with an average of .450 volts being perfect. the higher the volt reading the richer the car is and the lower, leaner. If you do not get these readings then that will have to be lesson #2. |

I'm very sure it was mentioned here before about the brand of sensors used. I wouldn't be surprised if it was a Bosch and I'm very sure that it can be picked up at an auto parts store. Try searching "oxygen sensor" using the keyword search on the left. |

There you go Tommy, Maybe there is a way to bypass those sensors, but some of those sensors send a message back to your ECU controlling fuel distribution and other important performance functions. I guess the thing to do is read the article and find out which ones are essential and which are not. |

THEIR IS AN ARTICLE IN FERRARI LINKS FROM A GUY IN HOLLAND DEALING WITH THE ISSUE OF THE EXTRA SENSORS ADDED TO JUST MEET U.S. EMISSIONS AND HOW ALL THEY DO IS ROB YOU OF POWER.ALSO COVERED IS HOW TO DISCONNECT THE PROPER ONES.

Call G.T. Car Parts 623-780-2200 and get a price on that sensor. Ask for Bill or Dave. |

I know, but your car is more high tech. than the older carbed 308s and with everything affecting the brain or ECU, I think I would keep all that connected. I'm sure some of these guys who know much more about the high tech end of it then I do will be commenting. That sensor monitors the rich and lean conditions of the exhaust. |

nothing yet. we haven't gotton that far. I wondered if someone was going to bring that up when I posted this question. I probably won't see my car for a few more weeks but I will let you know how it does.
Those sensors are expensive. If it isn't going to make a difference I hate to spend the money on one. |

Hi Dr. speaking of your O2 sensor being disconnected, what did you find out re: the rich eye burning smell. I don't think it would affect the performance but I would connect or replace it. |

My O2 sensor has been unhooked since before I bought my car 4 years ago. Should I fix it or forget it. There is no emission testing (thank God) where I live. Have I lost any performance with it disconnect? I mean any performance, not speed but fuel economy, etc. |
