On the 2.5 you have two prominent issues when it come to misfire. One of the injectors has burnt out (I have a write-up here how to check). You can find it in the tech section.
The other issue is a flaky distributor, distributor cap and/or rotor. Start with fresh rotor and cap and then go from there.

The weak valves and carbon build-up are bogus assumptions.
