These are coil on plug. With 11 years on the road and 120,000 - could definitely be one or more intermittently flaking out. They are pretty cheap for this car - like $25 or $30 each. So replacing all wouldn't break the bank.
A clear diagnosis "smoking gun" would be nice. But lacking that, no thrown codes to indicate anything but a random misfire, and given that you've already swapped plugs, I'd be inclined to go for the coils.
edit - see FASTFRED's post for add'l troubleshooting - good ideas!
