o2 sensor removal help
Yesterday i built a spacer for my second o2 sensor. when i went to install it, I was unable to remove the o2 sensor from the exhaust. we tried soaking it in PB Blaster (several times), open ended wrench, wrench + extension, socket + impact gun, heating + impact gun, and pretty much everything in between. anyone have a great idea of how to get the stupid thing out? i'm to the point i may just take it to a muffler shop and hope they can get it out without damaging the sensor (though i'm not sure its worth it, might end up costing more $ than it gains me in trade in value)
