O2 sensor

[Da808aZnRaVr]

ok i jus found out that i might have a bad O2 sensor...would anyone happen to know how much a new O2 sensor costs and if i would be able to install it myself...if i am able to install it myself would anyone be able to give instructions on how to do the install...thanks!!!

$17.50 from the local parts store. i have a `90, and from what i remember, you have an s14. maybe someone can explain the installation in detail. it was easy for my s13.

disconnect wire to o2
get the biggest vice grip you got
clamp that bitch at the bottom on the bolt looking piece
hit/bang/hammer/whatever it takes to get the thing off
tighten the new one on and connect wire

oh yeah it on the header...

I did this yesterday. &nbsp;a 7/8 wrench works perfect for removal and installation. <img src="http://www.zilvia.net/f/iB_html/non-cgi/emoticons/smile.gif" border="0" valign="absmiddle" alt=':)'> &nbsp;I got the one with the OEM plug attached so it was like $30. &nbsp;I think I ended up paying ~$10 for a rubber boot though, so.. &nbsp; &nbsp;

Do you know where it is? what do you know so we can fill in the blanks

I have a 95 SE and have had to replace both my 02 sensors on the header and the exhaust. &nbsp;Both were actually easy to do, good old crescent wrench but my only problem was on the install of the lower 02 sensor (exhaust). &nbsp;Apparently the o2 sensor that was installed prior had stripped the thread on the exhaust pipe. &nbsp;Bad thing. &nbsp;At this point I only had 2 options, new exhaust pipe from dealer (about 300-400 hundy) or try and find a fitting at the junkyard. Well one thing I found out was trying to find a 240 in a junkyard is a pretty rare thing. &nbsp;Personally I did not find any240 but Nissan uses the same size threading for all the sensors. &nbsp;So I bought one off an 88 Maxima, and had a shop add threading part to my exhaust. &nbsp;Labor and parts was 45 bucks.

20 for the Exhaust manifold from the Junk, and 25 for labor, ouch. &nbsp;So if you do not have any thread issues you should have no issues. BTY

Intake o2 sensor: 60-65 at the dealer. &nbsp;30 at the local part store. &nbsp;Dealer parts always recommended.
Exhaust o2 sensor - 80-85 at the dealer. &nbsp;Dealer part only
Hope this helps

Just thought I'd add that if you have an Autozone nearby you can rent an O2 Sensor socket kit for $15 and when you bring it back you get your $15 back. That socket makes it very easy for removal and installation.

Bosch makes great O2 sensors. &nbsp;They pretty much make one for every car.

They even have a heated 4 wire one if you ever run leaded race gas at the track.
