P0430 - bad cats from diesel contamination?

Had a CE on the way home last night. Code readers says P0430. Read what I could find here and took it to Indy this morn. He looked at the pre and post O2 readings and the driver side post was fluctuating up and down. Several months ago a gas station I used swapped the super with the diesel. They paid for (among other things) o2 sensors so I'm pretty sure it's not a bad sensor. Talked with Woody tonight, seems he has a drivers side cat I'm going to order.

We believe the diesel may have shortened the life of the cat but looking for other opinions. 143,xxx on an 03S. Thoughts?
