Battery on 2017 Silverado 1500 with AFM?
Hi all, I have a 2017 Silverado that I purchased in 2020. I believe it came with original battery. It has AFM (Automatic Fuel Management) changes V8 to V4 when on level or down hill grades). Lately, it was seemed to stutter a little when starting so I suspect it is the battery. This morning, because it was colder (below 40deg) it wouldn’t start. I jumped it and after driving it for 35-40 minutes, starts fine. I’ve never dealt with something like this and am wondering if I just need to replace the battery or if it’s more complicated than that?
Thanks!
