What wideband are you using? I got erratic reading like that when I did a free air calibration of the sensor while it was still inside the Y-pipe. After I removed the sensor from the exhaust and re-did the calibration It started working correctly.

decel is probably normal because of DFCO. The idle issue is not normal though.

Its an autometer wide band gauge. It didn't say anything about a free air calibration in the instructions. And what is DFCO?

It will almost completely cut fuel and retard timing.

Exhuast fumes will sit in there for hours and hours. Takes more than overnight of sitting.
