Hi, I'm Ron and I will be helping you today.
Stand by for a moment while I prepare your answer.

Expert:  rpmdiag replied 2 months ago.

Most commonly is spark plugs and coils, but if the misfires continue,check injectors too.

If there are still misfires, then check engine compression.

Thanks, Ron
