Hmmm...I have the part number in my shopping cart.
Part #: 12574976
Category: Emission Control System Hardware
and this from rock auto:
ACDELCO Part # 12574976
MODULE,PWRT CONT(W/O CALN) REQUIRES REPROGRAMMING
* Non-stock item--shipping delayed up to 3 business days
Can anyone else verify the PCM versus ECM...I'm sure that this is the correct part, but to clarify, I need the part that goes under the hood...and from what I understand, that is a PCM.
