Can you get some pictures of exactly where you are not getting spark? Are you pulling the spark plug wire off the coil and seeing if there is an arc?

If so then that would point to a coil issue as the crank sensor and cam sensor are not going to cause an issue on one or two cylinders unless there is an issue with the tone wheel.

We should also check for codes to find out if we have other codes then just misfire codes.

Below you will see a system overview that will help with a better understanding that this is literally just the coil and PCM that control the ignition system.

Let's start with this info and we can go from there.
