Intermittent miss up to 2k and idle when warm NA-T

[Travis89Turbo]

The GE originally had two single wire narrow band o2 sensors from the factory. About 6 months ago I bought an na header that had screw type o2 instead of the 2 bolt so I bought two brand new bocsh screw type o2 sensors. Ran great with no problems.

When I put he turbo and downpipe on I ran the two new o2 sensors. When the problem started o2 sensors were ny first thought so I pulled those two off and exchanged them under warranty. Installed them both and same problem.

The wideband is strictly for my AEM AFR gauge.

The current set up just so u understand how I have it hooked up is my wideband hooked up in one of the banks and then 1 of the new o2 sensors with both o2 sensor wires ran to it. When I have the ecu o2 sensor hooked in the front bank and wideband in the rear the car runs flawlessly. It certainly doesn't feel like im down a cylinder.

When I switch locations of the wideband with the same ecu o2 sensor now in the rear bank still with both wires hooked to it goes lean as soon as I fire it up.

The single wire o2 sensors have less then 15 miles on it.
