Howdy Curt, Sorry can't help not a tech. You should probably say how many miles you have. Certain conditions appear at different mileages. Also where are you located? The best GM tech I know has his own shop in Hopatcong NJ.
I am in South Dakota. The truck was bought originally in Tacoma Washington. She has a newer gm goodwrench engine just before my parent bought it 10 years ago. They put very few miles on it in the time they have owned it. This summer they bought a new sierra and didn't get what they wanted for trade so they sold it to me. They maintained this truck religiousely. So I am sure it isn't a major problem. I'm just missing something.
