WB02 or Datalog setup?

I have a classic fast seq unit in a friends car.

Sometimes, the wb02 is intermittant and will lock at 15.xx a/f the as if it's unplugged.

Sometimes, you can shut the ccom down, reconnect and the WBo2 is back... sometimes, you can unplug and replug the o2 and it comes back.. I just don't know what is causing it to go away and come back!

This was a new box to me, but it was used, no doubt.

Now I'm looking at two datalogs from his car. The WBO2 shows 1 for active and the O2 correction shows some correction -10% to -5% under power, but the actual A/F shows 0.

Is this a datalog setup error on the data logs?

On the intermittant problems, is this a WB02 that is bad? Just can't figure out why it works at times and others it doesn.
