Ignition Coil (3.7L)

Was is the life expentancy of the coils? While I don't get any error codes, sometimes it won't start when it's damp outside. Was thinking of replacing the coils. I have about 85K miles (135K KMs)

You can buy them at $15-$30 a piece and they're easy to replace.

when damp out, it sometime won't start on the first try. Any sense if failing coils?
