    o2 sensor, which one to buy??

    my o2 went bad on the way to work this morning, my question is do i buy one for a 2005 LQ4 (the motor in the car) or a 2002 T/A, the car itself.

    Strange no one else has chimed in on this one.

    If your running the factory PCM then I would guess you stick with a Delco Sensor. Some people switch to the Bosch since they have longer leads but I had trouble with them on my factory tune and went back to Delcos with O/2 Extensions.

    Really should look at what you have down there and try to match it.

    i will take one out and match it up, the 6.0 was already in there when i bought it, but i remember the owner telling me it was the factory LS1 pcm, with a tune and i have had a retune done on it as well, he also said i could take the 02's out and clean them with rubbing alcohol, any truth to that?

    Never have heard of doing that. I doubt the alcohol would realy clean up the carbon that much. It depends on how valuable $100 is to you Personally I'd throw on a brand new one and call it a day but if your time is no big deal the worst you can do is commit to buying a new one LOL

    Factory PCM, factory-spec sensors. At least, that's how I would do things.
