Not strange at all...And you driving for so long without fixing it does not help.
Will only get worst. Gas milage and performance are affected, not to mention you can do long term damage to sensative parts such as O2's and catalitics.

Most common source of missfire are plugs and ignition coils, mass airflow, and O2 sensors. After that it could be many things, but check the most obvious first. Trottle body is also known to fail a LOT on those cars.
