Did it fix your throttle problem? I'm having the same issue with my traction control and stabilitrak and loss of power during cruise speeds. I don't have the cruise on but just a low constant speed the truck struggles for speed. Also I'm not finding the part on amazon. I have an 08 Silverado. I called auto zone to and there saying part not yet available. What is the GM part number you got?

Yes traction control and stabiltrak comes on with ck eng. Then after setting over night it resets for a while then comes back on. The guy who owned it before me said he had tuned it so I don't know exactly what he set it too.
