I have a 06 gt and I replaced the plugs to motorcraft platinum. No problems until I got on it at it started to misfire on cylinder 4.

I hooked a noide light to the injector wires and cylinder 4 had a weaker pulse than the others.
And I checked the plugs just to make sure there was no cracks. And it is throwing code: p0354 but I'm sure the coil is fine.

I don't know how to go about fixing this.
Car isn't stock and any input is helpful at this point.

Have you tried swapping the number 4 coil for another cylinder and see if the misfire follows?

Pull the codes, it should give you some indication of the problem. Next step is swap coils or similar, as noted.
