Normal O2 sensor behavior at start up. Are mine shot? On my old stock engine I thought I remember the O2's reading around a constant 450v at closed loop on my scanmaster.
Mine now under the same conditions are reading different. The left at around 350V and the right is bouncing and the BLM's are acting strange all at closed loop.
Does this behavior at closed loop cold engine sound normal?

Well you said they are acting strange and startup but then you said closed loop. Car should be in open loop on start up while the O2s heat up then it will go into closed loop when engine gets warm.
