    I'm wondering if my crankcase evacuation may be causing an issue as well, since it's before the WBO2 sensor. I have one mounted in each header and the driver side is before the Sniper EFI WBO2 sensor.

    The header evacuation venturi pipe would have to be downstream of the WBO2 sensor.

    Wouldn't that cause weird AFR readings though, if it was an EVAC issue with the WBO2?

    I don't know what exactly happens because I wouldn't have installed the WBO2 sensor improperly.

    I didn't realize it was installed improperly due to the EVAC is to be mounted before collector and the WBO2 after the collector. It just dawned on me now that it may be an issue, depending on how much air/crankcase gases may be coming through the WBO2 sensor.
