Rich...lean...rich...lean......????

Can someone please have a look at this log and tell me if they see anything?
This just suddenly did this.
VE was dialled in pretty well prior to this whacky event this evening.
Have a look at the idling section at the end.
Didn't feel any different....no stumbles etc.

You need to log inj pulse width , and the factory O2 sensors for a sanity check.

Do you have the wideband directly connected to a good 12V source and a good earth ? a cig lighter socket is niether.

Thanks Delco,
I just ran a log upto op temp and don't see anything causing what I saw yesterday.
At the start of the log you can see the WBO2 drop out due to me unplugging it to check the connection. Also I see that when disconnected...it shows rich..not lean like I was seeing in the previous log.

Couldn't seem to replicate the problem.
