A couple of days ago my Front O2 sensor on the drivers side went bad. I don't usualy work on my car, but by looking at the new O2 sensor I got from AM it looks to be fairly easy since its plug and play and I honestly don't want to waste money on an install because Iam a student. I lifted up the car today and chickend out because Iam afraid of the car dropping on me and crushing my body. I bought Jack stands but I do not know where to mount them and while looking under the car I only saw the sensors connected to my midpipe. I know this makes me sound like a newbie but I want to know the exact steps I should take so I don't kill my self, but most importantly I do not want to cause any damage to my car.
