P0304 Code indicates a misfire on cylinder 4
Most likely causes for this are bad wire, bad spark plug, bad coil(s) or bad dist cap if so equiped.
A vacuum leak can also cause a misfire.
Seeing the vehicle is going on 13 years old replacing the wires and the plugs would be a good place to start, and could be the solution
