i install my new header and spipe. everything else went so smooth until it's time to switch the 02 sensor. after twisting and turning i finally got the 02 sensor, but the thread got so messed up. it wont lock in to the new header i install. i am running without the 02 sensor for the momment. local if possible if not i'm will to pay for shipping. thanks....

lol ur running with a gaping hole in your header? that's baller......

Is your car in limp mode? All i could think of is either use some threadlock glue or buy a new sensor from sparks

I did the antifouler trick on the spike sensor. You said thread lock what's that. The dealer is so expensive. Any other advise. And yes my car seems like in the limp mode. How long can I run like this

I had the same problem when i installed my headers. I had to go to the dealer and buy a new one. its the air/fuel ratio sensor you need to get if you go through the dealer. it should run you about $225 or around there.

just so i'm not making a jacka$$ out of myself, we are talking about the sensor on the header right? well anyway, threadlock is a general term for a glue that you put on the threads of a bolt to hold it in place after you screw the bolt into the fitting. it's basically permanent, so if you go that route, make sure the header won't be coming off anytime soon, if ever. i wouldn't run in limp much, and if possible not at all. not positive on what the effects are on the engine, but i do know your car will repeatedly stall out, since that missing sensor reports to the ecu your a/f ratios. lastly, i would highly recommend just buying a new sensor. it'll probably run you close to a hundred bucks but it'll save you of the headaches listed above. my $.02 anyway..

you can run it like that as long as you want, but your going to be really slow, and get terrible MPG cause your car is just dumping fuel.

you need one of these:

and treadlock is basically a glue used to help keep bolts from twisting out if you don't want them to.

thanks alot guys. for all the response. i'm going with the trd sparks sensor. thats the lowest price for a oem. i hope to get it really soon.....

Actually you need #7 from drax's link, the "air/fuel ratio sensor". (#6 is the narrowband O2 sensor for the s-pipe). The AFR which installs in the header is a wideband O2 sensor so it costs more.

BrownDogg was selling his sensor in the PPC Engine/Drivetrain Section... Look there before you buy anywhere else...
