Thanks Backyard (O2 sensor replacement)
Recap:... I had an intermittent problem with an O2 sensor, plus
possible fuel contamination. Ran out bad gas, ran "sea foam" through vacuum hose, and put some into gas. Made O2 sensor problem go away and car ran normal.. As per Backyard's suggestion that O2 sensors aren't made to last forever.. I changed all four of mine. I had 138,000 miles on mine in a 96 coupe. Now car seems to be more responsive than before (when computer wasn't in limp home mode..) $290 for parts and 15 minutes on the lift.. Now when I do have a problem or get a code... and least O2 sensors shouldn't be a problem for a while... Looking forward to checking milage on next trip.. Chuck |

I again thank the stars for my '67. I changed the O2 sensor in my Tempo at 124k. At 196k, she's no beauty queen, but 28-33 mpg is nice with gas prices where they are.

I again thank the stars for my '67. Welcome to dual exhaust OBD-II cars. My '97 Cobra is the same way. I'm afraid to see how much it'll cost for a round of sensors. The front two are calculated in the air/fuel mix... the rears are there to tell the computer that the cats are working. This is why there are a lot of O2 sensor eliminator kits for the rear two... > I changed the O2 sensor in my Tempo at 124k. At 196k, she's no beauty > queen, but 28-33 mpg is nice with gas prices where they are. Sensor. Singular. Must be nice... lol. Speaking of gas mileage, I hope it gets warm and dry here real soon so I can start riding the bike to work more often... > I had 138,000 miles on mine in >> a 96 coupe.

I had one o2 sensor go out around 50K on my 95GT, and the other sensor was still fine at 92K. Go figure. I DID see a test of o2 sensors somewhere a while back(I wish I could still find it) where someone hooked up a scope to them and tested their responsiveness. The older o2 sensors definitely showed a different pattern than the new sensors. Remove NO-SPAM from email address when replying |

The older o2 sensors definitely showed a > different pattern than the new sensors. They definitely slow up with age, but that largely depends on quality of the gas used, and a ton of other factors. It's deposits on sense elements that cause the slowing. Failure of "heater" element in the sensor is a whole different thing. May happen anytime -- - Yes, I'm a crusty old geezer curmudgeon.. deal with it! - |
