What model vehicle? What is the odometer reading? How long and how many km since the last service?
Things that can cause the problem you are describing are a problem with the EGR valve, improper ignition timing, a problem with the ignition system (coil, distributor, rotor, distributor cap, high tension wires, spark plugs), a vacuum leak, or a problem with the throttle cable.
It could be a primary electrical intermittent failure, or a fuel supply problem. Like Ray O mentioned, a bit more information would be helpful. Does the engine continue to "miss" when you push the clutch in and hold the rpm's at 3000, or only under a load? Do you mean that when you are accelerating above 3000 rpm it stops and then misses again when you stop accelerating and reach a steady speed?
