98 trans am with 99+ ECM harness.

Mice ate harness. Harness repaired.

Vehicle now has what appears to be an intermittent misfire.
It's not a consistent misfire - but it can obviously be felt while it's happening.
After driving the same plug is wet - and a temp gun shows it to be cold.

Haven't scanned it yet for a code.

I have all new coils to install - as I'm hoping it would be a coil.

Just wondering if the damaged harness could create this intermittent misfire?

Why not just swap that coil with another cylinder and see if the other cylinder is also staying cold. Then you can just buy one new coil.

A wet plug usually means leaking valve(s).
