I have a 2021 silverado custom trail boss with the 5.3, the truck has almost 8,000 on the odometer. I have installed a Flowmaster exhaust and S&B intake. Over the past couple of weeks the truck has randomly stalled out. Once at a red light, once while it was idling to warm up in the morning and once on a gravel road to the lake going about 5mph. As well as having a rough idle occasionally. Anyone else had this issue? And suggestions to what the cause could be?
