I'd suggest pulling the coil & checking the base for cracking.

"missing" under these circumstances is the first sign of a coil going bad. It's an unusual issue for cars in general, but we seem to see it fairly regularly on the Zetec's.

Search here a bit & you'll find some similar threads, "coil cracking" might find 'em.

Luck!
