Based on your readings, yes. However, if the check engine light is on, I recommend scanning the computer before replacing anything. There should be a code in the computer to identify where the problem is coming from. Most parts stores will do it for free, or you could rent a scanner from them.

Let me know what you find.

The OBD II troubleshooting code was PO353, ignition coil no. 3 primary circuit fault. The plugs are less than 2 months. Based on the readings earlier, should the coil pack be replaced or could something else be causing the readings?

That is what it sounds like. Make sure there is power to the coil.
