First question - what is the specific fault code? Cylinder misfiring can occur for a variety of reasons and conditions.

A fault code P0300 may mean that one or more of the following has happened:
Faulty spark plugs or wires
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector(s)
Burned exhaust valve
Faulty catalytic converter(s)
Stuck/blocked/leaking EGR valve / passages
Faulty camshaft position sensor
Defective computer

Be sure to take the time to thoroughly test and diagnose before replacing any parts.
