I was driving today and glanced at my wideband gauge and it was readying over 50...So I keep driving and a couple seconds later it goes back down to 12-13ish...It has never done this before and after this incident i kept my eye on it and it seems to be doing the same thing over and over going from 50 down to 13.

Any idea what could be the cause of this? I'm wondering if it has something to do with my fuel pump. It only does this when driving, the car idles fine.

 

What is your gauge/wb02?

 

It's a LC-1 and XD-16 gauge. I believe I bought it from you guys.


I went for a quick drive and the problem went away...I'm still curious about what could of caused this.

 

never seen 50. it should goto 40 when the sensor is unplugged I believe

 

Sounds like a grounding issue, the ground offset issue is big talk over on innovates forum. Where are the wires soldered / grounded to?
