Hi,

Is it possible (and I realize unlikely) that you got another bad coil? Try switching it with cylinder 3 or 4 and see if the misfire follows the coil. If it does, try yet another coil.

Let me know. Based on the description, I feel the same as you. It doesn't make sense.

Also, let me know if there are other codes that showed up.
