Mine runs better cold. When warmed up has rough idle at stop sometimes. I think I even heard engine knock before as if the timing is out sometimes. What could it be.

2001 suburban drive by wire, has a rough idle, just enough to let you know it’s not idling perfectly, and it’ll all of a sudden hesitate and bog down and it’ll die while idling, it’ll start right back up I can’t seem to figure out what the issue is, I checked fuel pressure that checked okay. I do notice that when it bogs down to die it tries to not die and it’ll knock a little like it’s pinging
