I think I'm going to roll the dice and buy a new A/F sensor. I already replaced the one on bank 1 when the heater failed. This one is still original with 120k miles on it.
What I did was get the obd2 scanner from Autozone from their tool loaner program. You pay $150 as a deposit and get a full refund within 90 days.
Thanks again.

what do you mean? are you saying that I should have replaced both when I replaced Bank 1? Or that I should replace both now?
Bank 1 a/f was replaced about 90k miles. Bank 2 is still original with 120k miles.

well like unohoo suggested, if you can afford it, i would replace both of them. the same thing for the knock sensors, their are two of them in these things. never replace only one, or you will just end up having to go in their again (trust me,its something you will only ever want to do once) with those sensors. some people believe that when you replace only one a/f sensor, it throws off the reading from the other one,and just fails shortly after. the a/f sensor is quite a high tech little sensor(not to mention the environment they live in),and would only recommend the original denso part.
