Hey Wolverine.......
Just saw you were having the same issue that I have been having with the 05 Grand Prix. I recieved a fix from another memeber that I wanted to pass along to ya:
Old thread, but thought it worthy of an update.
From surferstick:
I had the stock PCM reflashed to the updated code mentioned in the TSB. It's now been months, and not a single problem since, so this fixed it for sure. Even better, the car now feels as strong as my old 99 did. I always felt I lost some power when I traded my 99 GT for this 05 GT, and now I've got my missing power back too.
Happy New Year folks.
I haven't gotten mine flashed yet, but will check into it.
Just wanted to pass this along to ya.
Later....... Steve!
