You should pull the codes, ask for maintenance records (at 108k it is going to need a timing belt very soon figure about $800). Most likely the misfire is the coil packs (about $250 in parts).

Coilpacks are seldom the cause of a misfire and to have all four causing misfires is virtually improbable.

Have the cause professionally diagnosed if you lack the skill(s) or time.
Depending on what the service records indicate, I'd lean towards tight valve lash as the cause.
Obviously, without seeing the car, I'm just guessing.

How does the engine feel?
If it runs slightly rough at idle but smooths out at higher rpm's, I'd say valve lash is suspect.
