Can you tell us all your symptoms, and tell us everything you've done/changed? Sounds alot from your posts that you're chasing a gremlin. These sporadic posts all over are making this confusing.

Let'* focus in on this in one topic and nail it right the first time.

In my car whenever the idle get'* really lumpy or rough....and the SES light comes on....It only throws a O2 sensor code...So I'm going with yes...even though my sensor was not even in the car for 2 hours...it still does that

the only symptom is the the car has a rough idle when sitting, ive notice if the car is in park then the idle seems smooth, now if i put the car in drive and i have my foot on the brake the idle is a little rough, the car accelrates and drives fine its just has that bad idle when the car is at a complete stop i can even feel it on the steering wheel

Here is the AC Delco link.
http://www.acdelco.com/html/catalog/index.htm

I came up with ASF-75 but please double check that.

That is a good question about a O2 causing rough idle. So many things can cause rough idle on these motors.

The GM part number for you O2 sensor is also posted in TechInfo. You can use that number to order it from gmpartsdirect.com.
