O2 Sensor!!! Need HELP!!!

[97S14SR]

This week my O2 sensor went bad in my redtop. Car runs really rich, gas milage dropped from almost 400 miles/tank to just over 300/tank and loss of power. Want to know where I can get a new O2 sensor. Need the "fattie" sensor for my megan turbo extension. Let me know where I can get one.

get one at any auto parts store for a 80 sumthin 200sx turbo

you might have to extend the plug

you got 400 miles to the tank?

[97S14SR]

If I filled it to the top I would get closed to 400 somewhere in the 380 or more miles on the highway and around town I would get something like 325. That all chaged as soon as I put the other o2 sensor in. My advice is don't buy used o2 sensors.

regaurdless of what everyone else says, you can use a 91-94 Sentra Se-r O2 sensor. using one on my aftermarket j-pipe, car runs perfectly fine, no SES/check engine light. The Se-r sensor is a 3 wire plug that clips right in to the stock plug. i paid like $61 for a new one from autozone.

i run a universal 4 wire bosch sensor and have never had an issue. just spliced on the stock plug and ran the extra signal ground that the 4 wire sensor has and it runs like a champ.

don't do that... get something thats made for at least an SR. like i said, its a 3 wire like the stock one, the same length as the stock one, threads into an aftermarket j-pipe, and plugs right into the factory harness, no cutting or splicing at all. plug up and screw it in. took me less than 5 min to change it.

So it doesn't matter which one I use. A lot of people have been telling me to get a 300ZX sensor. Others have been telling me to get one specifically for the SR. This is just frustrating cuz I am not getting a consistant answer.

okay, read the words i am typing... just use a 91-94 Sentra Se-r (sr20de) o2 sensor. It is a 3 wire plug just like the stock sr20det one, its the exact same length, plugs right into our harness, and fits directly into our aftermarket j-pipes. i am using this and it works perfect. don't buy anything thats not made for a sr for one, and don't hassle with something you'll have to cut, splice, and ground something out, more than likely, you'll end up having a problem with that overtime. listen bro, no more headaches, 91-94 Sentra Se-r works perfectly fine.

Sorry to bump this but the 91-94 SER o2 is A FATTY type? Correct?

[g6civcx]

Correct. You can also use one from a 1990 to 1996 Nissan 300ZX Twin Turbo. It's the same.

If you need the reducer bolt to mount a skinny sensor into an opening meant for a fatty, PM me. I have a couple extra ones lying around.
