I'm trying to replace my front o2 sensors and so far I've only tried to get the drivers side one off with no luck. I have sprayed some PB penetrating oil on it and i still can't get it off. Any other tips? Part of my problem is I'm only working with the car up on some small ramps so I don't have a ton of room. I'm a little concerned about this too because the other one is even harder to get at and I wanted to replace it as well...

What are you useing? Wrench or O2 sensor socket?
Actually i got them both out, what I did was cut the wires and then slipped a box wrench around them to loosen them up. It was a tight squeeze but I managed to get them both replaced pretty quickly using this method.
I forgot to mention, the only reason I had to cut the wires was because the connector piece wouldn't fit through the box wrench.
Sooo use the open end of a wrench... And a hammer to get the breaking power. You gotta have short/quick blows to knock them free. .Thats the easiest method I've come across.
or get an 02 wrench..
I ground down the head of an open end wrench to fit. Takes a little muscle but works every time...
