Hi folks I hope you can help me with my problem. I recently bought a sierra denali 2008 and I was very happy with the truck, I love everything of it but something is bugging me.two weeks ago I found a list in this site about the RPO codes and its meaning so I went to my truck and started getting every code until I found this L92(Gas,8 cyl,6.0L, SFI Alum. Cyl deactivation HO GM). Now my question is doesnt the sierra denali supposed to have the engine 6.2L or Im wrong? I know I don't have the option to deactivate the cylinders in the DIC, so what engine do I have in my truck? Thanks in advance for the info.
