Good. The extended cranking is a bad fuel pressure regulator so I was trying to rule that out as a bad regulator could cause the engine to run lean also.
I recently replaced my lower O2 sensor as well. I bought the "exact fit" Bosch from Advance Auto Parts so I wouldn't have to splice the generic one into my existing harness. If money is tight the generic works just fine though. Replacement was fairly easily as long as you have the correct wrench. I couldn't get the special O2 socket to fit so I used a 3/4" wrench from under the car.
