my check engine light in on it says the car is misfiring
check your spark plugs, coils and make sure your Catalytic converter is good
With 5 years on the clock, I would change the plugs. You have to take the plugs out to check them anyways. Might as well install a new set.
I'm with tenspeed, change out your plugs and let us know if that seems to fix it
