That makes sense, bank 1 could be holding back while bank 2 is ramping up. Would definitely give a wide variance number. I'll head that direction.
No way to test the actuator without the PST2 scanner is there? I have a standard OBDii scanner. That will only tell me where the problem is, not what's causing it.
