Question Rough Idle

My wife's '93 Escort (125000 mi.)with 1.9 engine has developed a rough idle. I thought at first that the plugs might need replacment, but there is no miss at speed or upon acceleration. If I bump the engine speed up to about 1000 rpm (no load), the miss disappears. The miss does not seem to be on every revolutation, but somewhat less frequently, such as every 4th go-around. Anyone have any suggestions?

How's the condition of the rest of the tuneup items? Start there along with a scan of trouble codes at Autozone and let's go from there.
