So I was looking to change the bank 1 upstream o2 sensor. Got the stang jack up and on stands real quick thanks to you guys. Crawled underneath, looked up, and wondered how the fuck I was supposed to get that sensor out. I could barely get a wrench into the little space and I just couldn't get the fucker off. I've heard stories about it beind a bitch but I didn't think it would be that difficult. I'll give it another shot on a warmer day..
