Many rough idle problems are the result of burned valves. At a higher speed, the engine may not seem to be running rough, but may still be misfiring. On the other hand, if a valve is only slightly burned the cylinder may actually fire. It can also be a bad sparkplug, wire or distributor cap. In any case, you'll need to find out which cylinder is misfiring. If you've encountered a misfire problem that seems difficult to track down, run a compression test and see if all cylinders are ok. If the compression is up, track down other possible problems.
