i have not yet located the second but there is a way to bypass the knock sensor to kill that code right? are those instructions in this forum?

On the GTE block the #1 knock sensor is located between cylinders #1 and #2. The #2 knock sensor is between #5 and #6. On the GE there is only one located between #3 and #4.

No, you can't bypass it... not without a lot of creative electronics (see custom).

It's more likely that the ECU running in limp mode (that's what you're experiencing by the way) has killed the O2 sensor. The O2 sensor is the least of your worries. I'd just unplug it for the time being.
