so i installed some strup headers on my tc last nite but my friends and i couldn't get the o2 sensor off the stock header. we tried doing everything but it just didn't move. i am probally going to buy a new one. but until then, is it safe to run the car without an o2 sensor?

 

no its not safe to run without an o2 sensor. You may need to get something like penetrating oil to get it to budge.

 

very simple..

get either wd40... or penetrating lube... u can also get anti seize (all can be bought at autozone etc)

spray on the sensor and let it soat for about 10 minutes.. slide your socket wrnech on it and it should twist of much easier... you can also get a metal pipe and slide it over the wrench to give you extra leverage...or similar to a breaker bar..

that should help.. new sensor costs 150 bucks so try it before u go breaking ur bank...

 

150?

i found one for $35

sorry i only use OEM parts like that...u can take ur chances with a 35 dollar sensor if u want..not me IMO

 

from what i've heard, it is a hit or miss whether or not a universal o2 sensor will work. if somebody can prove this wrong, go ahead.

 

you have to wire it up with your old clip.. the problem is sometimes those universal o2 sensors 1. are cheap and burn out quickly. 2. 4 wires are in 2 colors lol so u dont know which wire is which most of the time... so u might wind up rewiring it 4 times at most before u get it right lol

 

Dont pay under 85 for even a universal o2 sensor, splicing them into the old clip is complected enough besides the fact that that one probably doesn't come with a splice kit your goning to have a lot of problems just get some Wd-40 and a o2 sensor socket and break it loose

 

its stripped pretty badly

 

i had to get a new sensor... its actually the air/fuel sensor... and it is 236 with tax at toyota...

 

ahh if it is stripped get the SAE equivalent of te metric size in a crescent wrench and knock it on with a rubber mallet and get it off.

 

update:

i was able to get it off. used a blow torch and it came off. i hope i didnt damage it . im gonna put it on in about 20 min. i let everyone know how it goes tomorrow

 

ahh a blowtorch never fails, as long as you didnt hit the actual sensor or wires iut should be fine.

 

Hey while we're on the subject of o2 sensors, do any of you know if installing a cat-less exhaust manifold will throw a check engine light with the second sensor in the downpipe? just wanting to know if any of you guys have ran into this problem. Hopefully it doesn't throw a code because I can get a good header and downpipe for cheap.

 

it is a toss up is it will throw a code, but it can be fixed easy, just use the search for antifouler fix

 

where do you get these antifoulers from?????

 

holy crap i had no idea they cost that much

 

wow u just paid almost double what it should be.. you just got anus raped on that bro.

 

autozone

 

update:

i got the o2 sensor on and it works yay!!!!

thanks for all ur input everyone
