You might put some B-12 injector cleaner in the next few tanks to help. I would say you are probably burning the old fuel and once it is entirely cleaned from the system it will be alright.

The problems you detail don't really add up to make any sense to me, either, but my guess would be the PCV valve is pulling too much oil and the O2 sensor is slow, a common GM problem. I hope this helps. Another really common problem is a leaking base gasket for the TBI unit (vacuum leakage).
