You must be thinking of the MAF. It's nothing like that.

 

Ya I had the problem with one of my o2 sensors. My passenger side was easy. Yes you can use ramps and jack the back up. I went to autozone and they had two different types of sockets. Get the shorter one of the two. I had the longer one I was tougher to because it was closer to the chassis. If you have a problem with the o2, get pb blaster. Heat it up and cool then spray. I got the Invidia ones btw. Oh ya before you put the o2 into the new midpipes just turn it 4-5 time counterclockwise then screw it in. It will be a little tight but your wires will be straight once it's tight. I reused the gasket at the end of the oem midpipe and put it on the new one. It's a good idea to get anti-seize also just in case. I did because I'm gonna get Ppe headers in the future.

 

I do it all the time. I'm an automotive technician and use that trick on just about every o2 I remove. do it while the exhaust is till warm and it will come off much easier. How would you know if you never tried it?

 

You may want to wear some mechanics gloves and be careful of how hot it becomes.

 

Is there a pic of this sensor on the forum somewhere? so i can get an idea of what im going to be dealing with.

@Bunthakey

Never tried it but i was just assuming

 

When in I get home I can

Thx it's cold outside lol

 

Question- Would it be easier to un-clip the O2 sensors prior to unscrewing them? How about unclipping them, take off the midpipe then unscrew them once the midpipe is on the ground/away from the car?

 

^^^ ya it would make it alot easier but itll take alot longer the same time, to unclip the sensors, ur gona have to remove both driver and passenger seat, then ur gona have to push it out, not worth the effort imo

 

thanks for the pic vinconist, it was a very nice day today but i didnt have time. Lets see what i can do tomorrow

 

Wow, thanks for the clarification, scratch that idea then...

 

i had a question. If i unscrew the O2 sensor should i take out the rubber holder from the bottom of the car so the wire of the O2 sensor wont mess up???

 

will doing this trigger any warning lights on the dashboard?
