Nissan sentra 2003 difficult first start, drawn spark plugs and code P0132

Question

Hi,
My 2003 Nissan Sentra starts with rough idle or doesn't start at all. When it starts, the rpm is irregular and I see a lot of white smoke (too much gas?) until the engine is warm. After warming, the engine works perfect and starts easily after a short pause. If it doesn't start, all the spark plugs are drawn in gasoline. Replacing the spark plugs make the engine start for the moment. I think the car starts easier at cold exterior temperature...
I have only 2 DTC codes: P0132 and P0031 and I think both refer to the oxygen sensor. Can the O2 sensor be the cause? (the previous owner said that there was a problem with the O2 sensor for a long time but the car ran well).
Thank you Reynaldo for answering me a previous question.

Answer 1

No, the O2 sensor shouldn't cause that problem. Your problem spound more like a blown head gasket, which is common on the Sentra. Try letting you Sentra sit for a few hours and then remove the spark plugs and check for coolant inside the cylinders, that's and indication of a blown head gasket. You can also try performing a compression test.
