7.3 knocking?

So Im at the drive through the other day and I noticed the engine making an intermittent knock. I would describe the sound like a......a knock, doesnt sound like a rod knock, almost like a pre-detonation. It'll do it 4 or 5 times, then nothing 2 times, nothing 6 times, just comes and goes. 240,000 miles on what I believe to be stock injectors, is it time for new ones? Thoughts?
