Yes, it is troubling having these code coz the OBDll Reader will show you a generic code which I also faced. Misfires mean vacuum leaks, fuel injector's problem, lower fuel pressure, weak ignition coil, bad plug wires, compression problem and dirty MAF sensor. Check intake vacuum gauge if needle is jumping up and down(17 to 21) and its hose and connections, and the throttle body, manifold and PVC valve; check fuel pump coz it may have a low voltage, its relays and wirings;check for possible obstruction on the fuel line like plug and filter; also, you may have a bad fuel pressure relay to the injector(dirty injector). Check if you have a clean EGR valve coz it might have accumulated carbon, and, PVC valve, too.
