2. Is it safe to just remove the code?
3. Will it come back in case the the problem comes up again (thus indicating that I need to either replace the plug or the coil pack)?
Thanks!

Hello, Im having misfires issues so I have a small amount of experience.
To answer your questions.
1, The DME shut off your #1 injector when the misfire was noticed. This is to prevent raw fuel from getting into the cat converter. Once you shut off the motor the DME reset and allowed the injector to operate normally.
2, Yes its ok to remove the code.
3, Yes, if the failure happens again you will get the light and the code will be stored.
