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.

 

Here's a screenshot of the idle section....but the whole thing is out of whack.
Could it be my PLX WBO2?

 

That is a sign of an O2 sensor going bad from what I've read.

 

Yeah...I'm thinking maybe the the WBO2 sensor is acting up.
I'm running OLSD so it's not the NBO2's but I'll use them as a cross reference and log some more data

 

Knew I'd read something like it.

That was the first thing I was looking for. Although, nbo2's look like hell in most modded trucks in OLSD. LOL But you'd be able to see the ripple the wideband was doing in comparison with them if it was real. I'd doubt it was real as you'd have to notice something in the rpm, engine sound...something in the engine.

 

Thanks guys.
That HPT thread sounds like it to a 'T'
I'll log today with the NBO2's as a comparrison and see what happens.
Actually...here's a 'warm-up' log which shows all is fine...damn it!
We'll see how it looks after driving.
Rich fluctuations at the start are me unplugging the WBO2 to see what it would do.

Any way to 'clean' the WBO2's?

Oh...see my sig for details of mod's. (running OLSD) 2 bar

 

Just ran a 30min (or so) log.
Couldn't duplicate the issue!
Damn! Can't upload the log...725K
