Small "pop" in the exhaust

[lukecp]

I was running my engine (350) in park today, and around 1500-2000 rpm i hear a pop noise in the exhaust, kind of like the noise you will get when you are driving around, and let off the gas and de-accelerate. I am thinking it is a problem with the plug wires, i noticed that one of them (#3) was sitting on my headers. I proably fried it, but i want to make sure. What else could do this? Vaccum leak, distributor cap or ? The plugs, wires, cap and rotor are all about a year old.
