It only takes a single cylinder with a compression issue to affect the idle and low RPM smoothness. The "puffing" noise you mention in the exhaust is a clue. If the other cylinders are operating normally, you'd fully expect the engine to start normally, just with that one chugging cylinder. A 4 or 5 cylinder engine would be harder to start with a weak hole, but a 6 will still fire right up if the other cylinders are healthy and the glow plugs work.
Take the time to diagnose. Crack injector lines to isolate the problematic cylinder, then dig in further.
