I need to replace the "upstream" O2 sensors. Only one is bad but with the car being 10 years old (only 60k miles though), I figured it would be good to replace both while we are at it.

Parts searches show O2 sensors ranging in price from $20 to $240. The cheaper ones don't have the OEM plug of course so have to be spliced in. Will there be any difference in the performance (of the car or the sensor itself) between the one I am looking at on ebay for $33 (no plug - must splice in, ebay item #370680278494 ) and the the Bosch 15627 ($200 on ebay)or the Denso 2349016 ($284 on Rockauto)?

btw - love this site and it has saved my *** many times and many $. Thanks to all of you.

 

That's quite the jump between $20 and $200 ... nothing in between?

If you plug each part number into the search box you might find other threads naming the sensor to read other experiences.

 

That helped. Punched in Bosch 15627 to the search and found another thread. This part has the proper plug which as someone pointed out may save a spliced wire from melting on the exhaust. I did find find the Bosch on Amazon - hope they ship to Canada.

 

OK. SO the Bosch 15627 02 sensor on Amazon for 89.99 - they won't sip to Canada. I ended up finding a Denso. Part Number: ND1937862 for 82.66 on Autopartsway.ca. I'll let you know if it fits. For all of you Canadians out there, I have had good luck with this company getting parts at great prices.

Now, if I can just figure out why I am getting a front end shake at 55 MPH!!

 

It's got to be wheel balance n' est pas?

 

It feels just like an out of balance wheel except I have had them checked three times. The shake is not consistent either. It comes on at about 40 mph and get most noticeable at 55 then is less or not noticeable at about 70. Even at 110 I can't really feel anything. Almost feels like something in the suspension is loose/worn. I have recently replaced wheel bearings (front), sway bar bushings and lower ball joints. Only 60k miles on car. The suspension is also a little "clunky" when I hit bumps. Just a mild thud (dont you love trying to describe car sounds) not metal on metal sounding - almost like a spring seat is worn but my mechanic can't find it. I'll need to get him out for a longer drive with me next time (when O2 sensors arrive)

 

Glad we could help initially Tibow and thanks for the kudos to the site.

Any joy with the suspension issue?
