Default Misfiring - Opti time?

Service Engine soon light came on this AM.
Pulled the codes and I am getting misfires on multiple cylinders.

With 78,000 miles on the car I think it is Opti time.
I tried to look around the waterpump and can see no leakage but I can't be sure.

I wanted to go with Dynatech but for $599 vs $297...
I will probably change the waterpump and plug wires at the same time.

Anything else you think it can be?

are your plugs original? if they are, replace them with NGK's...

also, check your coil wire. you live in CA, so moisture isn't such a problem.
