O2 Sensor Problem

[jah2707]

I can't get my upstream O2 sensor out of the down pipe. I even went to an exhaust place in town and they can't get it out! They said I would have to get a new one. I need it out to put in my new hotshot header. A new sensor is $120 at least. I was wondering if anyone knew of a way to get my old one out, or a cheap place to get a new or used one, or if I could just cap off the hole and not even need the sensor? I already have one so why do I need two? Thanks for any help.!

you have to have that one in there. Your car will not have the right A/F ratio without it. I know there is a O2 simulator that you can use, but why you would want a fake sensor and not the real thing, I don't know. I need to replace the same sensor, and AutoZone told me $90 for the thing. I hope mine comes out, otherwise I'm going to get headers sooner than I thought
