A Question About Wb O2 Readings

Hello Members.

I happened to snag an NGK AFX on the cheap and NIB. Will work on getting HPtuners Pro soon, but did a tidy install on the WB. Sensor is mounted on the passenger side about 6in. down from the original O2 and rotated about 60 degrees inward so the two sensors are not inline. Buttoned the exhaust up with new o-ring gaskets and do not detect any leaks at that joint. Followed up with the fresh air calibration.

 

Typically what I see on the display is 14.35 - 14.55. It wanders up to 14.7 then bounces down or it wander down to 14.25 then bounces up. This is at idle and hwy speeds.

 

My question: Is this nornal from the display cause it may not read as fast a computer would. Or should the reading be more inline with 14.68 and I need to look else where for a problem.

 

Thanks in advance for any suggestions. :chevy:
