I had the same problem recently. Checked the usual suspects for a missing cylinder...plug, wire, cap. I found a lot of play in the rotor, and the distributor is worn. Replacing the rotor, and adjusting the points resolved most of the problem. It still misses occasionally at idle, so I plan on replacing the distributor too. I'm guessing the accumulation of factors caused the miss. Why it occurs on #6, I can't say.
