No where near as easy to replace as you told me. When I changed the oil on Saturday I found the O2 sensor on the bottom before the catalytic convertor (I have a 95 so I believe there to be only that one) and neither me or my girlfriends brother-in-law could even get a crescent wrench, regular pliers, or needle nose pliers around the bolt part of the O2 sensor. It is at such an awkward angle and there is no room to put pliers, just barely a hand and Im not strong enough by hand to twist that darn thing out. So your observation that the O2 sensor "should take me a half an hour at most" is quite out of range. But thanks anyways, guess I'll be taking it to a dealer. But I really appreciate the help guys!
