The EGR Valve can cause a rough idle if the valve is open at idle, but this is not common. You should have a check engine light on if that is the case, is it on?

If you have a misfire, I wouldn't start with the EGR Valve or the MAF Sensor. Misfires can be cause by several things, spark plug, ignition coil, injector or a vacuum leak primarily. Here is some info on the misfire code, http://repairpal.com/OBD-II-Code-P0301 Read this for a better understanding, but I wouldn't start replacing parts, I would pay for a diagnosis and then replace what they say is bad.
