Quick o2 Sensor Questions

[Newlin]

The check engine light came on and I've had trouble starting every time so I took it to Auto Zone today and the codes told me that the downstream o2 sensor was bad. Now I figure I'll just replace both while I'm here.

Both Advanced Auto Parts and Auto Zone quoted me about $75 for each but I've been searching online and I've found some that are cheaper such as this one (http://www.amazon.com/ACDelco-213-96...ie=UTF8&psc=1).

My question is then is this one even heated? And would this fit both the up and down stream? Otherwise I'll probably jut buy them later today at Auto Zone and install them tomorrow night.

Uhh it should fit if its made for your car and work fine.

My autozone it was 55$ my 02

down steam 02 sensors shouldnt effect engine driveablity/starting. you could completly remove them and have zero negative effect other then a check engine light.

Another reason to have the 3400, your o2 sensors are cheaper

I might just grab them from Auto Zone after class. I'm driving her down to Detroit this weekend and I'd like to have it done as soon as possible.

Hmmm, it's only had trouble starting two or three times since yesterday so perhaps that's something else entirely.

Buy them at Advance Auto online using promo codes from retailmenot. You can save a bit if you use the right codes.

I ended up getting them on Amazon for the same price as Advanced Auto with promo codes. I would have gone that route but my local store didn't have the downstream in stock.

Either way I got both for about 90 USD and they should be here tomorrow. Hopefully we have some anti-seize lubricant lying around.
