Replace the coil pack... to confirm this pull spark plug leads off the coil pack one at a time.... note whether the idle changes. the spark will actually arc and you can hear it. if one of the plugs does not have this arcing... the coil pack is at fault.

Please take a moment to rate this solution.. thanks

Check for the computer codes. It can point to the cylinder that is miss firing. Could be a bad injector. Do a cylinder balance.
