Answer
It sounds like the injectors on the right bank maybe staying open.
All six injectors have a constant voltage applied to the brown/red wires, the other side is connected to the computer which opens and closes a ground connection to turn the injectors on and off. The #1,3,5 injectors are on the same wire that goes to the computer.
Check the white/red wires on the injector connectors and make sure there is no continuity to ground, if there is the injectors will stay open all the time.
Disconnect the connectors from the computer and see if the ground condition goes away, if it does the problem is the computer, if the ground is still there there is a problem somewhere in the wire harness that is causing this wire to be grounded.
