CHECK ENGINE REPORTS O2 SENSOR

2000 Saturn SL2

Engine Performance problem
2000 Saturn SL2 4 cyl Front Wheel Drive Automatic 80000 miles

Symptoms:
Muffler rattling all the way up to pass. Floor board.
Engine flooded little while back and changed spark plugs.
Burns Oil 4 qt at 2500 miles (assuming different issue)

Checked:
Air filter

Changed:
Spark plugs
Gas Filter

I don't think it is gas filter change but can't recall if it happened before. I was thinking of checking the exhaust line. Might be as easy as changing the O2 sensors?

What you mean muffler rattling all the way up to pass floor board?

What seems to be the problem?

Do you have gas in your oil? I mean raw gas.

Black exhaust smoke? Blue exhaust smoke? Rotten egg smell in exhaust?

The Check engine keeps firing off the O2 Sensor. The car runs pretty rough compared to 1 year ago. Gas seems to burn fine with pretty normal exhuast. By burn oil I mean draining oil doesn't yield much during oil change. 8 qt burn off during 5000 miles.

Yes you can feel the vibrations from the exhaust at the floor boards.

Sorry if previous message was confusing.
