Just wondering if this helped your problem. My wife's '01 LT is experiencing the same problem along with a hesitation at idle. It has just started.....only stalled once while parking. I just got back from running to the store and the hesitation at idle happened to me. I asked her about it and that's when I found it had stalled once.
I'll do a search for the TSBs. Any site better than the others?
Thanks in advance.
