Seen it several times.

Coils with butterscotch lettering are old and were replaced with blue lettering.

I have some F8DC4's NIB if you are interested send me a PM.

Good luck!!!
Plugs are new.. Iíll check things out and look closer. Itís a very weak misfire.. kinda like a hiccup now and then. Only noticeable under load when driving. nothing at idle or even reving in park.
