Occasional miss after warm

[BryanB]

Something else this 91 is doing, after it is driven far enough to warm up there seems to be an occasion miss. I feel it when sitting at a traffic light. It idles smooth and then it feels like a dead spot. It will do this every 5-10 seconds or so. Clears up when driving or at least seems to. No codes though. I'm still going to do plugs, wires, cap and rotor.

Been doing some research here and other forums. Sounds like my miss/stumble could be from dirty IAC. Going to tackle that this weekend and see if it helps
