o2 sensor
 

my friends o2 sensor went out in his 1991 EX 2door.

how hard is this to fix? is there a how to somewhere?

thanks ben

this is just a guess: if i a 02 sensor goes out i think u gotta replace it...mine went out a couple months ago and i had to fork out 80 bones for a replacement...i dont think there is a way of fixing it

you really have to change the o2 sensor in the car. there is no way around it

Which o2 sensor? I don't know about the '91s, but I have several on my car. From what little I know, there's no way to fix a faulty o2 sensor, you just gotta bite the bullet and buy a new one.

there is only one on the exhaust manifold. it's an obd1

i know i have to replace it.

he just doesnt want to pay labor to fix it. i was just wondering if you guys had a how to for it.

if you know anything on replace it and how or were to get a good one, please let me know

thanks ben

u need to buy a small part...it's a socket that's had one side cut into it so you'll be able to put that over the o2 sensor. Mine was really a ***** and then it broke and broke into pieces...let's hope yours it's as rusted as mine was. It's pretty easy if your exhaust manifold looks in good shape. Just get the socket and turn toward the engine and it should unscrew...if it doesn't want to come off...try NOT to force it off that's what happened to me..good thing my macanic broke it not me so he just took a torch to it and after 30min he got it off....we both got scared when it snapped. hope u have better luck

well you need to let the engine warm up a bit before trying to remove it, otherwise the sensor will be a ***** to take out.

My car already change the o2 sensor.

Yeah my car was really hot when i changed mine..i burnt myself like 10 times when trying to change it by myself...that's before the machanic got it done correctly.

we got it changed. damn it was kinda a *****. i didnt know it had to warm up. damn thing was hot i think we let it warm up to much i still got burn marks.

thanks ben

lol...yeah i had nice burn marks on my arm after that day i changed mine

i still got a small burn mark on the area between thumb and finger on right hand. and on fore arm. it sucks, looks like a huge hickie mark.
