Usar Google Translator para eso.....Try switching out #4 sparkplug first. If P0304 still exists, try switching coils to a different cylinder and see if the misfire follows the bad coil. Chances are it's a coil. #1 Cylinder is nearest to the radiator, #6 in order is at the firewall. Buenas suerte!

Heavy Vibration Engine

many of these vehicles usualy have arking ignition coils and faulty plugs due to coils ( arking at porcelain) pull coils and remove boots then check spark plugs, posible leaking valve cover gasket if so clean spark plug holes from oil and debris before removing spark plugs or it all goes inside combustion chamber. related codes for misfire are po300-po304, crank position sensor could be a problem, if you have code present check engine control module connector ( ecm located on passenger front foot area under carpet) check connector for loose or corroded contacts.
