2017 XLT with P0355-00 code

[DeanHCMA]

Hello, I'm new here and look forward to exchanging information and learning. Current issue is a 2017 XLT trim model, throwing up a check engine light, a P0305-00 and P0355-00 code. The person who used the vehicle noticed the idle issue, ran the vehicle until the # 5 coil cooked and popped the ignition coil fuse. The coil and fuse were replaced, checked the plug (replaced it) and it seems the last resort is a wiring issue. Where do I proceed from the connector to the #5 cylinder coil?

This us what the #5 cylinder coil looks like...

Welcome to the Forum Dean.
Not being a mechanic, I'll leave the answers to the more knowledgeable members. Good luck.

Which engine? Need that in order to pull the correct diagrams.

For a coil to cook like that usually means that either the wire between that coil and the PCM or the PCM's internal driver circuit is shorted to ground.

Thank you ProjectSHO89! I checked continuity for the wires to the coil and suspect the PCM.

Update on issue to ProjectSHO89, the harness feeding the coils was rubbing on metal and created a short for the #5 cylinder coil, in route from its origin. If I sould have checked for continuity of the electrical feed from the coil to the point of feed origin.

Lesson learned.
