I was driving my Buick on saturday and the O2's dropped to 000 and BLM's went to 90 when I came to a stop and it was idling but when I took off the car sputtered a second like it was running rich and once I got rolling a couple miles per hour or RPM past 1200 or so it smoothed out and the BLM jumped to 128 and O2's bounced around like normal. Think the O2 sensor is going out or something?
