Re: O2 Sensor replacement
I've done this twice now on facelift cars. The DR side is easy, the Pass is very difficult to access, it's much easier on a 32v engine.
When I changed the Pass CAT on my wife's car, I found that you might be able to access the sensor through the tie rod cutout and by removing one of the splash shields up top. I haven't actually done it this way though.
I used a LONG 1/2" extension with an impact gun to get them out. It's such a tight fit on the Pass side, it's an 1/8 turn going back in.
They're quoting you OEM sensors which actually make it more difficult. It's easier to use the Bosch universal connections that re-route the existing wiring, at least on the Pass side. They're around $80 a piece.
6 hours seems like a long time though. It's a 3 hour job, tops.
