Okay. Was it doing the misfiring before you changed the parts?

No, it was running fine. Then one morning it heard a squeaking sound and it started to shake and the check engine light started flashing.

I am sorry, yes it was misfiring before we changed the parts.

Does it misfire under power if so, then I would check the compression to see if all cylinders are okay it could be an injector,
here are two links that can help you
