The O2 voltages are fine for monitoring what I need to see....right now.

Not trying to be a knucklehead, and I appreciate all the replies and people trying to help me, but whatever is going on here, basically stops the O2 sensors (both) from moving at all. A WB isn't going to tell me anything different, except an actual a/f ratio which is not what I need to know. I need to figure out what the cause of the O2 stagnation is.

I am not doing any tuning, yet. I'm just trying to figure out what is happening here, and why it is happening. Both the STFTs and LTFTs are pegged full rich when the O2's stop moving. I see +20.3% on the STFTs (which can't go any higher), and I cannot remember what the LTFTs are at the moment. Unfortunately, I cannot view the HPT scan from work PC.
