Last summer, My wife limped it into the shop with a plug that had blown itself apart & I was told they replaced all 6 plugs and put a used wire in to replace the one connected to the blown plug. I was under the impression it was the #2 plug but may be mistaken.
Any quick thoughts?

May be either one.
What kind of plugs did they put in in?
On a 3.1 always go for a good set of plug wire when ever the plugs are replaced.
A bad plug wire will make them go crazy.
If it is arcing replace the hole set and have a look at the plugs to.
And make sure to use the AC delco plugs the good book calls for.
