Thanks for the help

How much did you end up having to pay for the sensor?

[Todd O]

I payed $197 on E-bay.

Not a bad price. I only wish I have bought more of those sensors 4 years ago. I bought 4 of them at $107 a piece. And to think, they were used for tuning turbo cars with the DIY WB kits, lol. the good thing was I still had one left when I finally got my VX and needed a new O2 for it.

Hi, I currently own a 96 civic HX and believe my oxygen sensor is giving out wrong readings. Not sure how I can check this, but after I've seafoamed the car through the pcv valve and the gas tank, I had my mechanic change the timing belt, water pump, spark plugs, oil change, coolant flush.

Problem is that I smell unburnt gasoline during start up. The car also feels as if it might have lost power. Does this mean my car is running in rich mode? How would I be able to check?

I've connected the OBD II reader to my vehicle and it doesn't give out any codes. Would this issue be related to the oxygen sensor? Does seafoam affect the oxygen sensor in any way? My car is getting about 35mpg mixed driving with 96,000 miles.

I have also found the universal 5-wire wideband sensors on ebay for about $56, however, from what I've read so far, it looks like it won't work.

Thanks for any info you guys can provide!

Even if your sensor isn't good, you really shouldnt smell unburnt gas. I would suspect a gas leak somewhere.

If your mileage is 35 MPG mixed, and the car has no check engine lights, sounds to me like your sensor is fine.

When the car goes into lean-burn, it actually feels slower, so that might be what you are feeling. WHen it goes out of lean-burn, you will feel a small push of extra power.

Thanks for that info. I've just contacted another party, and as it turns out, the NTK and BOSCH oxygen sensors operate on different technologies although both are 5-wire wideband. Those from BOSCH offered at $56 are designed for Volkswagen.

I don't quite feel any power pushes so I don't think it's in lean-mode. Well, I smell the unburnt gas when turning my car on for a minute and backing it into my driveway. Am I the only one who smells that rich gasoline smell when turning on my car in a compact area?

Living in a small and busy city (San Francisco), traffic is pretty much everywhere. I'll try driving more conservatively and see how the mpg turns out.

I didnt want to start a new topic on one that has been covered. I have the problem with the smell of unburnt gas (running rich) & mid 30's mpg. I am in the process of running it down now. first is going to be setting the ignition timing then new tps (already ordered figured couldnt hurt) then I would like some answers. She has had a full tune up. There is a new 5 wire o2 not put on by me & they tied in a 6th wire on to an existing 5 wire harness. the extra wire is a yellow with black stripe. Thanks
