Hey,

Thanks to a few of you on here who have been saying how easy this is, I got under my Max and replaced my right front O2 sensor (bank 1) last night. It was a little rusted, but with some force I unscrewed the old one, screwed in the new one, fed the wire up on top of the engine, unplugged the old one, plugged in the new one, and ALL SET. Anyone who has 1/2 hour or so to do this should do it themself - don't pay a dealer to do this for you. I saved about $160 - just had to buy the sensor.
